Question

The length of a hall is 10 m more than its braadth find the length is 600 m

Answer 1

Step-by-step explanation:

actually the area is 600m so let the breath be x so

length is 10+x

area is length x breath

but area = 600m

x(10 +x)=600

x²+10x -600=0

x²+30x -20x -600=0

x(x+30)-20(x-30)=0

(x+30)(x-20)

x=-30 or x=20

therefore the length of the hall is 30 cm and the breath is 20 cm
