Answer:
40 meters is my answer
Explanation:
if the diagonal is 85 and the length is 75
take the Pythagorean theorem, sqrt(a^2 + b^2) = C
C is equal to 85 as B would be equal to 75 to find A you would do the reverse. i think....
I did:
85*85 = 7225
75^2 = 75*75 = 5625
then i did basic math, 7225 - 5625 = 1600
now what number multiplied by its self equals 1600
40, So
40*40=1600
therefore 40 meters is the answer.
