The length of a rectangle is the square root of 100 times an unknown number, x. the width is one-half an unknown number, y, less three-halves x. if the area of the rectangle is 125 cm2, find an equation that would give the width of the rectangle given the length.

step-by-step explanation:

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
