Question

Construct a word problem on quadratic equation so that one

answer will be 15 ( age , metres, speed, rupees, etc ) . Solve the

problem you have constructed​

Answer 1

Answer:

length =2 m ,breadth =3 m and Area =156 sq.

we know that

Area of rectangle =l*b

so, the new area of rectangle =(x-2)*(x-3)

15=x2-2x-3x+6

x2-5x-150=0

IN quadratic equation

x2-15x+10x-150=0

x(x - 15) + 10 ( x - 15 )=0

(x -15 )( x+ 10 )=0

x = 15 , -10

since x is the length, it cannot be negative.

So original length =15 m. answer
