Question

the perimeter of rectangle math is 297 cm. the ratio of the length to width is 3:8. what is the width of the rectangle?

Answer 1

Width = 108 cm

Explanation:

Perimeter = 2 x (length + width)

297 = 2 x (length + width)

148.5 = Length + width

Ratio of Length to Width = 3 : 8

Sum of ratio = 11

`Length = (3)/(11) * 148.5 = 40.5 \ cm\\\\Width = (8)/(11) * 148.5 = 108 \ cm`
