Answer:
33 by 45 meters
Step-by-step explanation:
The perimeter is twice the sum of adjacent side lengths, so the sum of the dimensions is 78 meters. If x is one of the dimensions, then 78-x is the other, and the area is their product:
x(78 -x) = 1485
Subtracting the left side, we get ...
x^2 -78x +1485 = 0
This can be graphed as ...
y = x^2 -78x +1485
and the zeros will reveal the dimensions.
The attached graph shows them to be ...
33 by 45 meters
