If m=12 in and n= 14 in, what is the surface area of the geometric shape formed by this net?
A.
450 sq in
n. 444 sq in
C. 204 sq in
D. 480 sq in​

Answer 1

Answer: D

Step-by-step explanation: To find the area of a triangle, you multiply the base and the height, then divide by 2, but because there are 4 triangles, you can multiply 12 and 14, and then multiply again by 2. For the square, 12 times 12 is 144, when you add 336 (the area of the triangles) and 144 (the area of the square), you get 480.

Answer 2

Your answer is (D) 480 sq in

12 Multiplied by 14 is equal to 168
And you Multiply 168 times 2 which is equal to 336

Then you Multiply 12× 12 Which is equal to 144 and you add 144×336
And that will give you the answer of =480
