## Falling_In_Katt one year ago ***WILL FAN AND MEDAL*** Find the total area the regular pyramid.

1. Falling_In_Katt

2. Falling_In_Katt

is that a regular square pyramid seen from above?

4. Falling_In_Katt

yes

do they mean surface area?

6. Falling_In_Katt

yes

ok :) let's first find the area of the base that would be a square with a side length of 4

Area of a Square = (side)*(side) = 4 * 4 = ?

9. Falling_In_Katt

16

good :) then let's find the Area of one of the Triangles :3 We need the height of it we are given that the hypotenuse is 4 and half the base (to make a right triangle) is 2 so square root of (4^2 - 2^2) = ?

11. Falling_In_Katt

12

square root of 12 that's right ^_^ it can be simplified to 2 squareroot of 3 then there are 4 triangles so times 4 gives us$\large 8\sqrt{3}$

are your options in decimals? :)
