The area of Mrs.Raders rectangular garden is 100 square feet. One side is a stone wall. She encloses the other 3 sides with 30 feet of fencing. What are the dimensions of her garden?
I have the length of the triangle to be 30-2x and the width to be x.
But soo how would you put that equation together?
Would it be x(32-2x)=100...cuz i cant get it to come out right.
It is not a triangle. The stone wall is one side of a rectangle, and the fence is the other three sides of the rectangle.
30=2L + W
W in the first equation, put that for w in the second. Notice you get a quadratic equation, solve it.
