Question

The length of a rectangle is 6 m less than three times its breadth. The dimensions of the rectangle, if its perimeter is 148 m, are
a) 54m,20m
b)14m,40m
c)54m,24m
d)54m,14m
(with formula)​

Answer 1

Answer:

let breadth be x

2(3x-6+x)=148

2(4x-6)=148

8x-12=148

8x=148+12

8x=160

x=160/8

x=20

breadth=20

length=54
