Answer 1

Step-by-step explanation:

the area of the hall is 238 sq metres, calculate its length and breadth. Solution : x(x+3)=238⇒x2+3x-238=0⇒x2+17x-14x-238=0. ∴ breadth = 14 m and length = 17 m.

Answer 2

Step-by-step explanation:

Let the breath of the rectangular hall be x meter. Therefore, the length of the rectangular hall will be (x + 3) meter.

A/Q

X(X+3)=238

x^2+3x =238

x^2+3x-238=0

x^2+17x-14x-238=0

X(X+17)-14(X+17)=0

X+17=0

X=-17

x-14=0

X=14(ans)

length=14m

breath=X+3

=14+3

17m

But the value x cannot be negative. Therefore, the breath of the hall is 14 meter and the length is 17 meter.
