Question 88

The sides of a rectangle of perimeter 52 meter are in the ratio 4 : 9. Then the area in square meters of that rectangle is

Solution

Breadth to Length ratio is 4:9

So let Breadth is 4x & Length is 9x

We know perimeter of rectangle is 2(L+B)

2(4x+9x)=52

26x=52

X=2

so Length is=9x=9×2=18

Breadth=4x=4×2=8

So area of rectangle is L×B

18×8=144 meter square.
