Question

The length of a rectangular field is 3 times its breadth. If the perimeter of the rectangle is 56 m, Find its length and breadth.

Answer 1

Let the breadth be x
So, the length will be 3c

We are given Perimeter of rectangular field is 56m

According to question


We know that
Perimeter = 2(L + B)

56 = 2(x + 3x)
56 = 2(4x)
56/2 = 4x
28 = 4x
28/4 = x

x = 7

Length = 3x
= 3 × 7
= 21m

Breadth = x
= 7

Length=21m
Breadth=7m

Answer 2

Answer:

Length = 21 m

Breadth = 7 m

Here is your answer
