Question

Suppose I want a garden with 400 square feet. Write an equation that can be used to find the values for x that will result in that area.

Answer 1

x^2 = 400 Ft^2.
X = 20 Ft.
Garden size: 20 x 20 Ft.

Any 2 numbers whose product equals 400 Ft^2 will give the required area.

25x = 400 Ft^2.
X = 400Ft^2 / 25Ft = 16 Ft.
Garden size: 25 x 16 Ft.

Answer 2

thank you so much, such a life saver
