Question

QNO2: The length of a rectangle is 6m less than three times its breadth. If its perimeter is 148 m, find
the dimensions of the rectangle.

Answer 1

Answer:

l=54 m

b=20m

Step-by-step explanation:

Let length=l

breadth=b

Given,

l=3b-6 and

perimeter=148m

Perimeter of rectangle=2(l+b)

2(l+b)=148

2(3b-6+b)=148

4b-6=74

4b=80

b=20m

l=3(20)-6=54m
