Question

Find the area of the shaded part

Answer 1

To find the shaded area, we must subtract the unshaded area from the total area.

Total Area:

`30*25=750`

To find the area of the unshaded rectangle, we must first find the length and width. To do so, subtract the smaller lengths from the larger lengths.

`30-8=22\\25-4=21`

The length is 22cm, and the width is 21cm.

Now that we know the length and width of the unshaded rectangle, we can find the area.

`21*22=462`

Now that we know the area of the unshaded, we can subtract it from the total area to get the shaded part.

`750-462=288`

The shaded portion is 288 cm^2
