A baseball infield is a square, each side measuring 90 feet. To the nearest foot, what is the distance from home plate to second

base?

3 0

Using the Pythagorean theorem:

90^2 +90^2 = X^2

8100 + 8100 = x^2

16,200 = x^2

X = √16,200

X = 127.28 feet.

Rounded to the nearest foot = 127 feet.

Help me solve this please

The key word here is *square* in "square flower garden".

So we need to find the area of the flower garden, and subtract it from the overall area of the yard. The remainder will be how much grass covers the yard.

Area of the Square flower garden:
7.5 * 7.5 = 56.25

Area of the Entire yard:
25 * 18 = 450

450 - 56.25 = 393.75 square feet of grass
