Question

Please help me if you can

Answer 1

Answer:

Area_3 = 25

Distance from Washington to Springfield = 70.7 miles

Step-by-step 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
