Question

The perimeter of a rectangle us 50 inches. The length of the rectangle is 10 inches. Which method can be used to find w, the width of the rectangle

Answer 1

15

you can use the equation p = 2l+2w to find the width of the rectangle

Explanation:

perimeter of a rectange p = 2l+2w

l = length

w = width

p = perimeter

it tells you the perimeter is 50 so p=50

it also tells you the length is 10

solve for w (width)

50 = 2(10)+2w

50 = 20+2w

30 = 2w

15 = w

width is 15
