Question : 10 of 40

Marks: +1, -0

If the perimeter of a certain rectangular field is 76m and its sides are in the ratio 9 : 10, find the measure of its shortest side (in m).

Solution:

Ratio of sides = 9 : 10
Perimeter of the rectangular field = 76 m
2(l + b) = 76 m
2(9x +10x) = 76 m
2(19x) = 76 m
38x = 76 m
x =

{76}/{38}

= 2
Shortest side = 18 m
