Question

the room is 5m longer than its breadth if the area of the floor ofguage the room is 150sq.m find the length of and breadth of roo explain in easy lan

Answer 1

let the breadth be x m

lenght=(x+5)

area=l*b

150=x(x+5)

150=x^2+5x

after factorising this we get,

b=10,-15

since b>0

so,b=10

l=15
