Question

obtain a pair of linear equations in two variables the length of a rectangle is one and half times its breadth. if the perimeter of the rectangle is 100 cm, find its length and breadth

Answer 1

Answer:

Step-by-step explanation:

Let

l=3/2b

perimeter is

2(l+b)=100

putting l=3/2b in above eq.

2(3/2b+b)=100

3b+2b=100

5b=100   ; b= 20m

l=3/2*b  ; 3/2*20

l=30 m , b= 20m
