Question

Length of a rectangle is 8m less than twice its breadth. If perimeter of the rectangle is 56m . Find its length and breadth

solve the above question n let me know the solution this question is taken from ch linear equation in one variable​

Answer 1

Step-by-step explanation:

let breadth be n

then length be 2n-8

perimeter of rectangle is2(l+b)

2(2n-8+n)=56

2(3n-8)=56

3n-8=28

3n=36

n=12

breadth=12

length=16
