The length of a rectangle is eight more than twice its width. The perimeter is 96 feet. Find the dimensions of the rectangle

blagie [28]

Step-by-step explanation:

Length = L

Width = W

L=8 more than 2W

L = 8 * 2W

L = 16W

Perimeter = 96

perimeter is the lengths of all sides added together

2L + 2W = 96

we have

L = 16W

2L + 2W = 96

let's do substitution

put what L = into 2L + 2W = 96

2(16W) + 2W = 96

can you rearrange that to get w
