Pam and Erin are both planting gardens for their backyards. They want their gardens to be proportional. If Pam's garden has a length of 16 feet and a width of 12 feet, what length does Erin need if the width of her garden is 21 feet? Explain how you determined your answer.

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

answer: 12x^2+6x

step-by-step explanation:

6x does not equal 24x. hope it works!
