Question

The length of a rectangular hall is 5m more than its breadth. If the area of the hall is 594 m2

,

find its perimeter.​

Answer 1

Answer:

98 m

Step-by-step explanation:

Let the breadth be x. So length is (x + 5)

Area of rectangle = length * breadth

594 = x(x+5)

594 = $x^{2}$ + 5x

$x^{2}$ + 5x - 594 = 0

$x^{2}$ + 27x - 22x - 594 = 0

x (x + 27) - 22(x + 27) = 0

(x + 27) (x - 22) = 0

x + 27 = 0

x = -27

But - 27 cannot be breadth as it's negative

so we take (x-22) = 0

x = 22

So, now we have breadth = 22 m

and length = (22 + 5) = 27

Perimeter = 2 (length + breadth)

= 2 (27 + 22)

= 2 (49)

= 98 m
