Answer:
Area_3 = 25
Distance from Washington to Springfield = 70.7 miles
Explanation:
Two
If one side of a square is 50 miles, all sides are.
a^2 + b^2 = c^2
You are looking for c. a and b both equal 50
50^2 + 50^2 = c^2
c^2 = 2500 + 2500
c^2 = 5000
√c^2 = √5000
c = 70.7 miles
One
Again you are using a^2 + b^2 = c^2
c = 169
Perimeter of square 2 = 48
a = ?
- a is square 3.
- b is square 2
- c is square 1
4s = 48
s = b = 48/4
s = b = 12
area_2 = s^2
Area_2 =12^2
Area_2 = 144
Area_ 1^2 - Area_2 ^2 = Area_3^2
169 - 144 = Area_3^2
side_3 = sqrt(25)
area= 25
