A school wants to build a rectangular playground that will have a diagonal length of 75 yards. How wide can the playground be if the length has to be 30 yards?
A rectangle has two diagonals. Each one is a line segment drawn between the opposite vertices (corners) of the rectangle. By using the Pythagorean Theorem, we can calculate the width. We do as follows:
c^2 = a^2 + b^2
a = sqrt( c^2 - b^2 )
a = 68.74 yards
Answer:
We should use Pythagorean's theorem. a² + b² =c²
Step-by-step explanation:
a² + b² = c²
75² = 30² + b²
5625 = 900 + b²
5625 - 900 = b²
4725 = b²
\(\sqrt{4725}\) = \(\sqrt{b}\)
68.73863542 = b
b = 68.74
