Question

Could someone help me with this. I don't understand this part of geometry.

In the center of town, there is a square park with side length of 30 ft. If a person walks from one corner of the park to the opposite corner, how far does the person walk? Round to the nearest foot.
A. 21 ft
B. 42 ft
C. 52 ft
D. 60 ft

Answer 1

It's a simple Pythagorean's theorem problem:

Answer 2

So you would have that
a=b
\[a ^{2} +b^{2} = c^{2}\]
so then
\[30 ^{2} +30^{2} = c^{2}\]
\[=1800^{2}\]
\[\sqrt{1800}\]
= 42.426

Answer 3

correct
