Question

this is rectangle breadth is 7cm and find length

Answer 1

length is equal to 13

Answer 2

Hii There!!

Given breadth (b) of the rectangle = 7cm
and Perimeter of the rectangle = 40cm
Here, length = x cm.

Since, Perimeter of a rectangle = 2 [ length+ breadth]

=) 40 = 2[ x + 7 ]

=) 40/2 = x + 7

=) 20 = x + 7

=) x = 20 - 7

=) length = 13
or. x = 13

Hence, length of the rectangle is 13 cm.

Hope it helps
