Question

The perimeter of a rectangle is 84 m. If its breadth is
17 m, find its length.​

Answer 1

Answer:

Perimeter of rectangle = 2(l+B)

= 2(l+17) =84

=2l+34 = 84

= 2l = 84-34

= 2l = 50

= l = 50/2

= l = 25

Therefore length = 25 m

Answer 2

Given:-

perimeter = 84 m

breadth = 17 m

We know that:-

perimeter of a rectangle = 2 ( l + b )

84 = 2 ( l + 17 )

84 = l + 17

2

42 = l + 17

l = 42 - 17

l = 25 m

Therefore, the required length of the rectangle is 25 m.
