Question

2. Find the area and perimeter of the rectangular shape below.6 m10 m4 m15 m

Answer 1

To find the perimeter of this rectangular shape, we only need to find two values:

These values are 10 - 6 = 4, and 15 - 4 = 11

Then, the perimeter of this figure is 10m + 11m + 6m + 4m + 4m + 15m = 50m.

The total area is the area of the blue rectangle and of the small red square:

`A_1=11\cdot10=110m^2,A_2=4\cdot4=16m^2\Rightarrow A_1+A_2=110m+16m^2=126m^2`

Then, the area is 126m^2.

In summary, the area of the figure is 126m^2 and the perimeter is 50m.
