Question

(i) The ratio of length and breadth of a rectangle is 3 : 1, and its perimeter is 36 cmn.
Find the length and breadth of the rectangle.

Answer please!​

Answer 1

let :Length [ L ]=3x

Breadth (B)=1x

perimetre=sum of all sides=3x+3x+x+x

36=8x

$\frac{36}{8} = x \\ \\ \frac{36}{8} = x = 4.5$

L=3*4.5=13.5

B=x=4.5
