Question

The area of s rectangular hall is 165 sq .m.if it's length is 4m .more than its breath what is the length and breadth of the hall

Answer 1

Step-by-step explanation:

area=165 m²

let breadth be x

length = x+4

area = L×B

=x(x+4)=165

= x²+4x =165

x²+4x-165=0

using quadratic equation we get,

x=11

so breadth =11

length =15

hope this will help you
