Question

Tasha is planning an expansion of a square flower garden in a city park. If each side of the original garden is increased by 10 m, the new total area of the garden will be 169 m2. Find the length of each side of the original garden

Answer 1

6m

Explanation:

To find the original length you must take away the add-ons. To do so we know that they added 7 and A= l*l (or l squared). They added the 7 to the length so multiply 7*7 (49) subtract your answer from 169 (120) and that's your new area. To find the original length divide by 4 (I believe) and get 30m2
