Question

The ratio between the length and the breadth of the rectangle is 5 ratio 3 find the length is 5:3 if the area of rectangle is 600 m

Answer 1

If the length of the rectangle is 3x

And the breadth of the rectangle is 2x

So, the perimeter of the rectangle is 2l+2b

100 cm = 2(3x)+2(2x)

100 = 10x

x = 10 cm

Now the area of rectangle = 3x * 2x

= 6x^2

=6(10^2)

=600 cm^2
