Question

Find the length of the rectangle with a perimeter of 200 cm and breadth of 10 cm.

Answer 1

Step-by-step explanation:

Given,

Perimeter of the rectangle = 200cm

Breadth of the rectangle = 10 cm

Therefore, by the problem

=> 2(l+b) = 200cm

=> 2(l + 10) = 200cm

$= > l + 10 = \frac{200}{2}$

=> l + 10 = 100

=> l = 100 - 10

=> l = 90

Hence, required length othe rectangle is 90 cm (Ans)
