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 class=

Respuesta :

Thdev
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.
