David has a garden with dimension 11 feet long x 9 feet wide. he wants to enlarge the garden to an area of 126. How much farther will he need to extend the length of the garden to attain his desired
Length = 11 Width = 9 Area we need = 126 So Area = length * width 126 = 11 * 9 Now.. this is obviously wrong.. they want us to find the correct length.. 126 = L * 9 126/9 = L L = 14 Now since they ask about how much farther you need to extend, take the final and subtract from the original 14 - 11 = 3 Answer is 3.
