It would be (x)(x+7)=170
If you want it solved, then you would get:
x^{2} +7x-170=0
(x+17)(x-10)=0
And since you can't have a negative length (-17), x=10
So your side lengths would be 10 and 17 (10+7), which would give you an area of 170.
Hope that helps.

Answer:

Step-by-step explanation:

Let the length of the rectangle be=x, then the width of he rectangle will be=7+x.

Also, we are given that the area of the rectangle is equal to=170 square meters, therefore

Area of rectangle=Length×Width

⇒170=x(x+7)

On solving the above equation, we get

⇒170=7x+x^2

⇒x^2+7x-170=0

which is the required quadratic equation.

⇒x^2+17x-10x-170=0

⇒⇒x(x+17)-10(x+17)=0

⇒(x+17)(x-10)=0

Since, he length of the rectangle cannot be negative, therefore the length of the rectangle=x=10 m

And, the width is=x+7=10+7=17meters.
