The length if a rectangle is 3 less than twice than the width. If the perimeter is 180 what is the width and length

Answer 1

Hi Riley H.,

Set the width of the rectangle to be x . Then express the other two math statements in the question as math equations. Solve the perimeter equation for x .

In detail: width = x

length = 2*x - 3

perimeter = 2*width + 2*length = you do the rest!

Answer 2

L=59, W= 31

they sum to 90, 90x2 = 180

59=2(31)-3

180=2L+2W =2(2W-3) + 2W

6W = 183

W = 31

L=2(31)-3 = 59
