Question

The perimeter of a rectangular park is 300 feet. The length of the park is 10 feet longer than the width.

Find the length of the park.
What is the length of the park?
feet=?​

Answer 1

80 ft

Explanation:

width = w

length = w+10

Perimeter of a rectangle

P = 2(l+w)

300 = 2(w+10+w)

300 = 2(2w+10)

Divide by 2

300/2 = 2/2(2w+10)

150 = 2w+10

Subtract 10

150-10 = 2w+10-10

140 = 2w

Divide by 2

140/2 = 2w/2

70 = w

l = w+10

l = 70+10

w = 80
