Question

the perimeter of rectangular field is 208 m . Its length is 8 more than twice its breadth. what is the length and the breadth of the pool?

Answer 1

The breadth of the pool will be 32m and the length will be 72m....

Answer 2

Let breadth of the rectangular field be B

Given that

Length is 8 more than twice its breadth

∴ Length = 8 + 2B

We know that  Perimeter of rectangular field = 2 (Length + Breadth)

∴ Perimeter of field = 2( 8 + 2B + B)

But Perimeter of field is given 208 m

∴ 2( 8 + 2B + B) = 208

8 + 3B= 104

3B = 96

B = 32

∴ Breadth of the field is 32 m

and Length = 8 + 2B

                     = 8 + 64  

                     = 72 m
