Question

The length of a rectangle is 8 in. more than its width. The perimeter is 52 in.

What is the length of the rectangle?

Answer 1

do you know the perimeter equation

Answer 2

it is p= 2w + 2l
w is width and
l is length

Answer 3

The length of a rectangle is 8 in. more than its width.
now translate this into the equation
Length = l
is mean equal sign
more than = plus
width = w
so
l = 8 + w

Answer 4

and perimeter is 52
so we can replace p by its value
2w + 2l = 52
now l= 8 + w is already solved for l so plug l value in to 2w + 2l=52 this equation where l is

Answer 5

now distribute bracket by 2
