Help ASAP please plz​

Part A
The area of one triangular face of the square pyramid is 320 square feet:

As shown in the net, use the side length 32 ft from the square face as the base of a triangle.

Use formula 1/2 • base • height to find the area of one triangular face:
1/2 • 32 • 20 = 320
FINAL ANSWER: The area of one triangular face is 320 square feet.

Part B
The surface area of the square pyramid is 2,304 square feet.

Add up area of each face in the net:
Area of the square base: 32 • 32 = 1,024
AREA- 1,024 square feet

We know that the area of one triangular face is 320 square feet. Since we have 4 triangular faces, we will multiply 320 by 4:
320 • 4 = 1,280

ADD area of squara base and area of 4 triangular faces:
1,024 + 1,280 = 2,304
FINAL ANSWER: the surface area of the square pyramid is 2,304 square feet

HAVE A NICE DAY!
