The perimeter of a rectangle is 154 the ratio of the length to the width is 10: 1 what's the length and width?

Perimeter of a rectangle is 154

let's take length and width as x so,

length = 10x

breath = 1x

Perimeter of the rectangle = 2(l+b)

154 = 2 (10x + 1x)

154 = 2(11x)

154 = 22x

x = 154÷22 =7

x = 7

length = 10×7= 70

breath = 1×7= 7
