Question

QI] Frame the equation using one variable:- The length of rectangle is twice its breadth. The perimeter of rectangle is 36cm. Solution:-
​

Answer 1

Answer:

let the breadth of rectangle =x

therefore length=2x

perimeter of rectangle =2(l+b)=36cm

2(x+2x)=36

3x=36/2

3x=18

x=18/3

x=6

now breadth =6cm

and length =6*2=12cm ans
