Answer:
Step-by-step explanation:
By the Pythagorean Theorem we know that the hypotenuse (longest side) squared is equal to the sum of the squared sides of a right triangle.
h^2=x^2+y^2 (where x and y are the dimension of the sides)
h^2=120^2+120^2
h^2=14400+14400
h^2=28800
h=(28800)^(1/2) yds (exact)
h=169.7 yds (rounded to the nearest tenth of a yard)
