The length and breadth of a rectangular park are in the ratio of 9:11. If it's area is 891meter square, find its perimeter |
|
Answer» length = 9x and breadth = 11X area of the reactangle = lxb 891 m sq = 9x X 11x 891m sq = 99x^2 891/99= 9 = 3 hence the value of x = 3 length = 9x3 = 27 breath = 11x3 =33 perimeter of the rectangle = 2[l+b] 2[ 27+33} = 2[ 60] = 120 m so the perimeter of the rectangle is 120 m
