Question

the length of a rectangular hall is 5 m more than its breadth. If the area of the hall is 594 meter square, find its perimeter.

Answer 1

Let the breadth be x and length be x+5

Area of rectangle =length * breadth

594= x(x+5)

594= x²+5x

0=x²+5x-594

0=x²+(27-22)x-594

0=x²+27x-22x-594

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

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

Then x=22 OR x=-27

Taking positive value of x,


x=22=breadth and then

Length =22+5=27

Perimeter of rectangle =2(l+b)

Perimeter of rectangle =2(22+27)

Here, perimeter of rectangle =2*49

Here, perimeter of rectangle =98m
