Answer:

I want to know the sides of a pizza if the width is 9 inches larger than the height and the area is 250 squared inches.

My brother wants to know how long his bed is if it has an area of 2m and the width is .5m larger than the height.

My father wants to know whats the size of a football field if the area is 57,600 square feet given that the length is 200 ft larger than the width.

Explanation:

To solve this you just have to think on the unknown value and represent it as "X" in the first problem we do not know the length or width but we have a values given between them, so if "x" is the height then the width becomes "x+9" so those two values multiplied become the area.

x(x+9)=250\\x^{2} +9x=250\\x^{2} +9x-250=0\\

With this you just keep solving the others.

My brother wants to know how long his bed is if it has an area of 2m and the width is .5m larger than the height.

2m as an area and the height is "x"

x(x+-5)=2\\x^{2} +.5x=2\\x^{2} +.5x-2=0\\

My father wants to know whats the size of a football field if the area is 57,600 square feet given that the length is 200 ft larger than the width.

57,600 is the area and width will be "x"

x(x+200)=57,600\\x^{2} +200x=57,600\\x^{2} +200x-57,600=0\\
