Given the perimeter of a rectangle garden is 104 feet and the length is 6 feet longer than the width. Find the area of the rectangle.

Question

The answer is 667 square units, but I don't know how they got it.

Answer 1

P=2l+2w

w=width

w+6=length

104=2(w+6)+2w

104=2w+12+2w

104=4w+12

104-12=4w

92=4w

w=92/4

w=23 feet

l=23+6=29 feet

A=lw

A=29*23

A=667 square feet
