Question

The length of a rectangle is 6 m less than three times its breadth. Find the dimensions of the rectangle if its perimeter is 148 m.​

Answer 1

let breadth = x

length = x-6

2x-6 = 148

x - 3 = 74

x = 77

b = 77

l=. 71

Answer 2

Answer:

perimeter = 2(l+b) = 148

b = x

l = 3x - 6

p = 148

2(l+b) = 148

l+b = 148÷2 = 74

3x-6 + x = 74

4x -6 = 74

4x = 74+6 = 80

x = 80 ÷ 4 = 20

so ur ans is 20
