Question

The length of a rectangular field is thrice it's breadth and it's perimeter is 240 m. The length of the field is? ​

Answer 1

Answer:

The length is 90M

Answer 2

Answer:

Length = 90 m

Step-by-step explanation:

Given that ;

Perimeter of a rectangular field = 240 m

Consider ;

Breadth of a rectangular field = x

It's Length = 3x

Perimeter of the rectangular field

( P ) = 2 ( L + B )

P = 2 ( 3x + x )

P = 6x + 2x

240 = 8x

8x = 240

x = 240 / 8

x = 30 m

Hence ;

Breadth ( x m ) = 30 m

Length ( 3x m ) = 3 × 30 = 90 m

Length of the rectangular field = 90 m
