Question

Find the area of the pyramid net

Answer 1

The area of the pyramid net is 12 units

Step 1

Find the area of the Square in the middle

Formula for finding square:

$A = L*W$

Let's apply the formula and find our answer:

$A = 2*2\\=4$

The area of the square is 4 units

Step 2

Find the area of all 4 triangles around the square

As you know, the formula for finding 1 triangle is as follows:

$A = \frac{1}{2} *B*H$

But, to find the area of 2 triangles, we can use this formula:

$A=B*H$

And to find 4 of them (with same dimensions;as required here), we can use this one:

$A=2*B*H$

Let's apply the formula then! What are we waiting for!!!!

$A=2*2*2\\=2*4\\=8$

The area of ALL of the triangles around the square is 8 units

Step 3

Add all areas to find FINAL ANSWER!

Easy!

4+8=12

The area of the Pyramid Net is 12 units

Answer 2

Answer:

12 is the answer because 2 x 2 = 4 but since it is a triangular face we half it and end up with 2, 2 x 4 is 8, the square it 2 x 2 = 4 so we add 4 and 8 which equals 12
