Question

b. Brooklyn runs 10 miles, the perimeter of arectangular park. The length of the park is 3miles. What is the area of the entire park?

Answer 1

The area of the park is of 6 squared miles.

Explanation:

Rectangle:

Has two dimensions. Length l and width w.

The perimeter is: P = 2l + 2w

The area is: A = l*w

In this question:

P = 10, l = 3.

First we have to find the width of the park.

P = 2l + 2w

10 = 2*3 + 2w

2w = 10 - 6

2w = 4

w = 4/2

w = 2

Area of the park:

A = l*w

A = 3*2 = 6

The area of the park is of 6 squared miles.
