Question

The top of the John Hancock Building is a rectangle whose length is 60 ft more than the width. The perimeter is 520 feet. What is the length?

Group of answer choices

a. L = 160 ft

b. L = 40 ft

c. L = 100 ft

d. L = 80 ft

Answer 1

160 ft

Explanation:

We have

2(length + width)= perimeter

than,

let, width =x

now,

2(x+60+x) = 520

or, 2x+60 = 260

or, 2x = 200

or, x = 100

so length is 100+60 = 160
