Question

Length of a rectangle is 10 more than its breadth. Perimeter of rectangle is given to be 100 m. Which of
the following will help to find the dimensions of the rectangle?
(Assume length of rectangle is x m)
(A) 2(x + (10 + x)) = 100
(C) Both (A) and (B)
(B) 2(x + (x – 10)) = 100
(D) None of these

​

Answer 1

Let the breadth of the rectangle be X

then length of the rectangle = 10 + X

Given perimeter of rectangle = 100

=> 2 ( l + b ) = 100

=> 2 ( 10+ X + X ) = 100
