Question

The length of a rectangular hall is 5m more than its breadth. the area of the hall is 750 m square. the length of the hall is

Answer 1

Let breadth = x m

Then, length = (x+5)m

Given that area = 750 m²

Therefore area = length × breadth = 750

=> x(x+5) = 750

x² + 5x - 750= 0

(x+30)(x-25)= 0

x = 25 or -30

Here -30 is not possible because the length never become negative.

Length = X+5 = 25+5=30
