The units for area always have to be ________
squared
200
What is the perimeter formula for a rectangle with sides of Length = L and Width = W?
One of the following:
P = 2L + 2W
P = 2(L+W)
or P = L + L + W +W
200
What is true about the base and the height for all triangles?
They must be perpendicular to each other.
200
What does b1, b2 and h stand for in the area formula of a trapezoid?
b1 = base 1
b2 = base 2
The bases are the parallel to each other.
h = height
200
What are the formulas for solving for the circumference?
List both formulas
C = πd
C=2πr
200
Find the total area. Use 3.14 for pi.
Rectangle area plus half circle area.
19x12 = 228 sq. ft
Half Circle: A= 3.14 x 62 = 113.04
113.04/2 = 56.52
Total Area = 228 + 56.52 = 284.52 sq ft
300
What is perimeter of a rectangle with length 8 cm and width 4 cm?
P = 8 cm + 8 cm + 4 cm + 4 cm
P = 2x8 + 2x4
P = 24 cm
300
Find the area
A = 0.5 x 14 x 5 = 35 units squared
300
Find the area of a trapezoid with b1 = 5 cm, b2 = 7 cm and h = 9 cm
A = (5 cm + 7 cm)9 cm/ 2
A = 54 cm2
300
What is the circumference of a circle with radius 5 cm?
Pi = 3.14
C = 2 * 3.14 * 5
C = 31.4 cm
300
What is perimeter?
What is 24 ft
400
If the area of a square is 361 square meters, what is the Perimeter of the square?
P = 19 x 4 = 76 m
Take square root of area to get side length.
Square root of 361 = 19
P = 4 x 19
400
Find perimeter.
P = 10 + 14 + 8
P = 32 cm
400
Find the area
What is 28 units squared
400
What is the area of a circle with diameter 18cm? Round to nearest hundredth.
A = 3.14 * 92
A = 254.34 cm2
400
If the minute hand is 5.5 inches long, what distance will it travel in one hour. Use 3.14 for pi.
C = 2 x 3.14 x 5.5
C = 34.54 inches
500
If the perimeter of a rectangle is 56 feet and the height is 7ft, what is the length?
Length = 21 feet
56 - 14 = 42 feet
42/2 = 21 feet
500
Find the height of a triangle with an area of 39.68 square meters and a base of 6.2 meters.
Height = 12.8 meters
500
Find the area of the trapezoid with b1 = 15 in, b2 = 20 in, h = 12 in.
A = (15 in + 20 in)12/2
A = 210 in2
500
Find the area of the shaded region. Use 3.14 and round to nearest tenths.
Area of big circle minus area of inner circle.
A big circle = 3.14 x 42
A big circle =50.24 in2
Area innrt = 3.14 x 12 = 3.14 in2
Subtract: 50.24 - 3.14 = 47.1 in2
500
Find the circumference of the shape. Use 3.14 for pi.
19 + 12 + 19 = 50 ft
c = 3.14 x 12 = 37.68
37.68/2 = 18.84 ft
Total = 50 + 18.84 = 68.84 ft
