Question

pls solve it....... ​

Answer 1

breadth = b

Length = 3b - 6

perimeter = 148m

perimeter = 2((3b - 6 ) + b)

148 = 6b - 12 + 2b

148 + 12 = 8b

8b = 160

b = 160/8 = 20

breadth = 20m

length = (3 × 20) - 6 = 60 - 6 = 54m

Answer 2

Answer:

Length = 54

Breadth = 20

Step-by-step explanation:

Let the Breadth be x

Length = 3x -6

2(L+B) = 148

L+B = 74

x + 3x -6 = 74

4x = 80

x = 20

Breadth = 20

Length = 60 - 6

= 54
