Area

100

• Find the area of a rectangle with length 8 m and width 3 m. Hint: Use the formula Arearectangle=length×widthArearectangle=length×width.

• 100: 8×3=24 m2

200

• A square has side length 7 cm. What is its area? 

 7(2)=49 cm

300

• Find the area of a triangle with base 10 cm and height 6 cm. Hint: Use the formula Area triangle=1/2×base×height

1×10×6=30 cm2

400

• A trapezoid has bases of lengths 8 m and 5 m, and its height is 4 m. Find the area. Hint: Use the formula Area trapezoid=(base1+base2)2×height

(8+5)×4=213×4=26 m2

500

A rhombus has diagonals of lengths 12 cm and 9 cm. Find its area. Hint: Use the formula Area rhombus=1/2×d1×d2

1/2×12×9=54 cm2

Perimeter

100

• Find the perimeter of a rectangle with length 6 m and width 2 m. Hint: Use the formula Perimeter rectangle=2(length+width)

2(6+2)=16 m

200

• A square has side length 11 cm. What is its perimeter? Hint: Use the formula Perimetersquare=4×side

4×11=44 cm

300

• The three sides of a triangle measure 5 cm, 7 cm, and 10 cm. What is the triangle's perimeter? Hint: Perimeter is the sum of side lengths.

5+7+10=22 cm

400

• A rhombus has side length 9 m. What is its perimeter? Hint: A rhombus has four equal sides, so Perimeterrhombus=4×side

 4×9=36  

500

• An isosceles trapezoid has non-parallel sides (legs) each of length 7 cm, and the bases are 12 cm and 8 cm. What is the perimeter? Hint: Add all four side lengths.

12+8+7+7=34 cm
