Question

The length of a square is six inches long.Kingsley drew a rectangle with the same area as the square.The length of Kingsley’s rectangle is nine inches.What is the perimeter,in inches, of Kingsley’s rectangle?

Answer 1

let breadth of rectangle is b

then

area of square = area of rectangle

6 × 6 = l× b = 9 × b

36 = 9b

dividing by 9 both side

36/9 = 9b/9

4 = b

b = 4 inch

so l = 9 inch

perimeter of rectangle = 2 (l + b)

= 2 ( 9+4)

= 26 inch
