Question

Find the area of each figure. Round to the nearest hundredth where necessary.

Answer 1

A = 1,307 cm^2

Explanation:

Formula of Surface Area of a Rectangle:

A = 2 (lw + lh + wh)

length*width = (20)(23) = 460

length*height = (23)(4.5) = 103.5

width*height = (20)(4.5) = 90

A = 2 (460 + 103.5 + 90)

A = 2(653.5)

A = 1,307 cm^2
