Answer:
1050m^2
Explanation:
Area of a rectangle = width * length
Length (any side doesn't matter) = 25m
Area = 12500m
By rearranging the formula, width = area / length
width = 12500 / 25 = 500m
sides are equal so it would be 25+25+500+500 = 1050m^2
THIS ONLY WORKS IF LENGTH IS IN METRES, YOU DID NOT SAY
