Answer:
it would be 9.6
Step-by-step explanation:
The surface area of the square pyramid net consisting of a square and four triangles is 380 sq. cm
<h3>How to find the surface area of a figure?</h3>
The surface area of a square pyramid is equal to the sum of the ara of the base square and the four triangle.
<h3>Find the area of the square base</h3>
Area of the base = 10cm * 10cm
Base area = 100 sq,cm
Find the area of a triangle
Area of triangle = 0.5 * 10 * 14
Area of a triangle = 70 square cm
Area of 4 triangles = 4(70) = 280 sq.cm
<h3>Determine the surface area</h3>
SA = 100 + 280
SA = 380 sq. cm
Hence the surface area of the square pyramid net consisting of a square and four triangles is 380 sq. cm

Answer:2 11/16 I believe is the answer
Step-by-step explanation:
Answer: 172 square centimeters.
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Area of a pentagon (A) = 1/2× 5s × a
Where:
s : side of the pentagon
a: apothem
Replacing with the values given and solving for A (area):
A =1/2 x (5 x10) x 6.88
A = 172 square centimeters.
