What is the area of a pentagon is the apothem of 12

thats your answer

Step-by-step explanation:

Start with the side length and apothem.

then  

Divide the pentagon into five triangles.

lastly  

Calculate the area of a triangle.

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
