Question

The perimeter of a rectangle is 45 inches. One side of the rectangle

is 5 inches. Find the area of the rectangle.

Answer 1

Perimeter of a rectangle = 2l + 2w

Since we know that l=5, we can say that:
2(5)=10

45-10=35 , which is the remaining perimeter aside from the 5-inch side lengths.

35=2w
w=17.5 inches

5*17.5=87.5 in^2

So, the area of the rectangle would be 87.5 in^2.

Answer 2

Answer: 17.5*5=87.5
