Answer 2

Answer:

${\sf{\boxed{\underline{Length=54m}}}}$

${\sf{\boxed{\underline{breadth=20}}}}$

Step-by-step explanation:

Let the breadth be x

and the length be 3x-6.

Given:

to find the dimensions where perimeter is 148 m.

We got equation:

$\sf[(3x-6)+x]=148$ m.

Solution:

⇒ $\sf[(3x-6)+x]=148$

⇒ $\sf6x-12+2x=148$

⇒ $\sf8x-12=148$

⇒ $\sf8x=160$

⇒ $\sf x=20$

so,

breadth is 20 m.

length is (20×3-6) 54
