community garden design

Math question on Pythagoream theoram?

")A square flower garden is being designed for the community park. The diagonal distance from one corner to another is to be 15 feet. What is the length of each side of the square? Round the answer to the nearest tenth of a foot.
10.6 feet
7.5 feet
12.8 feet
21.2 feet
"

10.6

if you draw a square and draw diagonal line from one corner to another (opposite) then draw another diagonal from another corner to its oposite = you’ll have four right angle triangles whose legs will be 7.5 ft, (half of diameter)
then use pytagorean thm to solve for it’s hypotenuse which is actually a side of a triangle
(7.5)^2+(7.5)^2 = 112.5, take a sqrt of it
a side of a square equals 10.6

or simplier a^2+b^2=15^2
since it’s a square a=b
so 2a^2 = 15^2
solve for x, you’ll get the same answer
