Question

find the surface area of the square pyramid. now, find the area of the 4 triangles. area of 1 triangle: 70 cm² area of the 4 triangles: ? cm²

Explanation:

Step1: Calculate the area of 4 triangles

Since the area of 1 triangle is \(70\ cm^{2}\), and we need to find the area of 4 triangles. We use the formula \(A = 4\times\) (area of 1 triangle).
\(A=4\times70\)

Step2: Perform the multiplication

\(4\times70 = 280\)

Answer:

\(280\)
