Answer:
30 ft wide by 35 ft long
Step-by-step explanation:
Let w represent the width of the garden. Then the length is (w+5) and the area is ...
w(w+5) = 1050
Completing the square, we have ...
w^2 +5w +6.25 = 1056.25
(w +2.5)^2 = 32.5^2
Taking the positive square root gives ...
w +2.5 = 32.5
w = 30
w +5 = 35
The dimensions of the garden are 30 feet by 35 feet.
