I hope i dont any mistake :p tell me if u dont understand :)
We know that <span>the given side lengths are x and the height is x.
Therefore, the area of the base = </span>

The answer is 6.25 square kilometres
one side is 1.25 and the other will be 1.25*4 =5
and for the area we multiply the two 1.25*5=6.25
Ln(x) should be the answer
