Question

the perimetre of rectangle is equal to that of a square with side 13m.if the rectangle is 16m long,what is its breadth?

Answer 1

Hii..

Here is ur answer :--

____________________

Given,

Perimeter of rectangle is equal to perimeter of square.

Side of square = 13m

Perimeter of square = 4*13

= 52m

So, Perimeter of rectangle will be 52m.

2(l+b) = 52m

=> 2(16+b) = 52m

=> 32+ 2b =52m

=> 2b = 52-32

=> 2b = 20

=> b = 20/2

=> b = 10m

Hope it helps!!

Answer 2

perimeter of rectangle = perimeter of square
perimeter of square = 4a
13*4 = 52
now, 52 = 2(l + b)
52 = 2(16 + b)
52/2 = 16 + b
26 = 16 + b
26 - 16 = b
10 = b
