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 = ?

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) = ?

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? :)

we will have to add that 8 root(3) + 16
