Write an equation to describe the situation.A garden is being constructed in the shape of a rectangle. Find the length L of the garden given that the length is 
greater than the width and that the area of the garden is 
.
A. L + (L - 10) = 170 B. L(L + 10) = 170 C. (L - 10) = 170L D. L(L - 10) = 170
