<u>Though there is no specific requirement, we'll compute the perimeter and area of the shown image.</u>
Answer:
<em>The area is 175 square inches</em>
<em>The perimeter is 60 inches</em>
Step-by-step explanation:
<u>Area and Perimeter</u>
We are given a compound shape and it's required to calculate its area and perimeter.
The perimeter is the sum of all its external side lengths. All of them are given thus:
P = 5 + 5 + 10 + 10 + 15 + 15 = 60
The perimeter is 60 inches
Now for the area, we split the figure into two rectangles, one of dimensions 5 in by 5 in (a square) and the other of 10 in by 15 in.
The total area is:
A = 5*5 + 10*15 = 25 + 150
A = 175 square inches
The area is 175 square inches
