Find the AREA

100

Find the area of the following rectangle.

L= 4cm

W = 8cm

32cm²

32 cm squared

32 square cm

200

Find the area of the following rectangle.

L = 8 meters

W = 7 meters

A = 56m²

A = 56 meters squared

A = 56 square meters

300

Find the area of the following square.

Side of Square = 5cm

A = 25cm²

A = 25 cm squared

A = 25 square cm

400

Find the total area of the two rectangles:

1. L = 3cm      W = 4cm

2. L= 4cm      W= 4cm

Hint: To find the total area you must find the area of each and then add them together.

1. A = 12cm²

2. A = 16cm²

Total Area ---> 12 + 16 = 28cm²

500

Find the total area of these two figures:

1. Square:  Sides = 2m

2. Rectangle: L = 2m   W= 4m

Hint: To find the total area you must find the area of each and then add them together.

1. A = 4m²

2. A = 8m²

Total Area ---> 4 + 8 = 12m²

Find the PERIMETER

100

Find the perimeter of the following rectangle.

L = 1cm

W = 2cm

P = 6cm

200

Find the perimeter of the following rectangle.

L = 6mm

W = 2mm

P = 16mm

300

Find the perimeter of the following square.

Square Side = 7m

P = 28m

400

Find the total perimeter of these two figures:

1. Rectangle: L=2m W=5m

2. Rectangle: L=3m  W=1m

Hint: To find the total perimeter you must find the perimeter of each and then add them together.

1. P = 14m

2. P = 8m

Total Perimeter --->14+8 = 22m

500

Find the total perimeter of these two figures:

1. Rectangle: L = 5cm  W = 6cm

2. Square: 9cm

Hint: To find the total perimeter you must find the perimeter of each and then add them together.

1. P = 22cm

2. P = 36cm

Total Perimeter ---> 22+36 = 58cm

Area/Perimeter

100

What is the formula for the area of a rectangle?

A= L x W

Area = Length x Width

200

How do you find the perimeter?

Add up all the side lengths

300

The area of a square is 16m².

What is the length of each of the sides?

All 4 sides are 4m

A = l x w

16 = 4 x 4

400

The perimeter of a rectangle is 20mm.

The length is 4mm

What is the width?

The width is 6mm

20 - 4 - 4 = 12

12/2 = 6

500

The area of a rectangle is 28cm².

The length is 7cm.

What is the width?

the width is 4cm

Area = length x width

28 = 7 x ?

Perimeter: Find the missing side

100

The perimeter of a triangle is 16 km, the length of the two known side lengths are 5 km and 4 km. What is the length of the unknown side?

7 km

P = s + s + s

16 = 5 + 4 + ?

200

Perimeter of a regular pentagon is 30 m. What is the length of one side of the pentagon?

Hint: A regular pentagon has 5 equal sides.

6 m

6 + 6 + 6 + 6 + 6 = 30

5 x 6 = 30

300

The perimeter of an irregular 4 sided shape (quadrilateral) is 36 mm. The known side lengths are 6 mm, 11 mm and 15 mm. What is the length of the unknown side?

4 mm

36 = 6 + 11 + 15 + ?

400

A square has a perimeter of 16 cm. What is the length of one side?

Hint: A square has 4 equal sides

4 cm

P = s + s + s + s

16 = 4 + 4 + 4 + 4

500

A rectangle has a length of 8 cm and a total perimeter of 26 cm. What is the width of the perimeter?

Hint: P = l + l + w + w

5 cm

26 = 8 + 8 + w + w

Area: Find the missing side

100

Area of rectangle = 56 m²

length = 8 m

What is the width?

7 m

56 = 8 x ?

200

Area of rectangle = 96 cm²

width = 8 cm

What is the length?

12 cm

96 = 8 x ?

300

Area of square = 144 mm²

length = 12 mm

What is the width?

w = 12 mm

144 = 12 x ?

400

Area of rectangle = 99 m²

length = 11 m

What is the width?

9 m

99 = 11 x ?

500

Area of rectangle = 147 km²

width = 21 km

What is the length?

7 km

147 = 21 x ?
