Question

The diagonal of a rectangle is 1meter more than its length and breadth is 1meter less than its length. Find length and breadth

Answer 1

Answer:

Let the length be L.

so,

(l +1 )^2 = l^2 + ( l - 1)^2

l^2 + 1 + 2l = l^2 + l^2 + 1 - 2l

l^2 + 4l = 0

l ( l + 4) = 0

l = 0 or l + 4 =0

l = -4
