The perimeter of a rectangular garden is 90 meters The lengt

The perimeter of a rectangular garden is 90 meters. The length is 6 meters longer than twice the width. Find the dimensions of the garden. What is the width? m

Solution

let length be x and width be y

then as per question,

x=6+2y

and perimeter=90

hence 2x+2y=90

x+y=45, x=45-y=6+2y

3y=39

y=13

hence x=45-13=32 answer
