a school wants to build a rectangular playground that will have a diaonal length of 75 yards. how wide can the playground be if the lenght has to be 30 yards
You would use the Pythagorean Theorem. a2 + b2 = c2 302 + x2 = 752 900 + x2 = 5625 900 – 900 + x2 = 5625 X2 = 5625 √(x^2 ) = √5625 X = 75 It is 75 yards wide. I've included a drawing of the rectangle if it helps.
