Basically, you just have to find the length of the rectangle that is 27 x 78 feet. The equation for the diagonal: d = sqrt(l^2+w^2) l = 27 w = 78 plug them in and solve d = sqrt ( (27^2) + (78^2) ) d = sqrt ( 729 + 6084 ) d = sqrt ( 6813 ) d <span>≈ 82.5
The ball traveled approximately 82.5 feet from one corner of the rectangular 27 x 78 foot field, diagonally to the other side.
