Front

What is the formula for calculating the perimeter of a rectangle?

Back

Perimeter = 2(length + width)

Front

What is the formula for calculating the surface area of a rectangular prism?

Back

Surface Area = 2lw + 2lh + 2wh (where l = length, w = width, h = height)

Front

What is the definition of perimeter?

Back

Perimeter is the total distance around the outside of a shape.

Front

What is the definition of surface area?

Back

Surface area is the total area that the surface of a three-dimensional object occupies.

Front

If a rectangle has a length of 10 ft and a width of 4 ft, what is its perimeter?

Back

Perimeter = 2(10 + 4) = 28 ft.

Front

If a rectangular prism has dimensions 5 ft, 3 ft, and 2 ft, what is its surface area?

Back

Surface Area = 2(5*3 + 5*2 + 3*2) = 62 ft².

Front

What is the perimeter of a square with a side length of 6 in?

Back

Perimeter = 4 * side = 4 * 6 = 24 in.

Front

What is the formula for calculating the area of a rectangle?

Back

Area = length * width.

Front

What is the relationship between the perimeter and area of a shape?

Back

Perimeter measures the boundary length, while area measures the space within the shape.

Front

If the base of a triangular prism has a base of 8 cm and a height of 5 cm, what is the area of the base?

Back

Area = 1/2 * base * height = 1/2 * 8 * 5 = 20 cm².
