Above are two different models of the same triangle. If the area of the model on the left is 20 sq cm, what is the area of the model on the right?

The area of the model on the right is 80 sq cm

Step-by-step explanation:

Since the scale for the model on the left is 1 cm = 5 ft, and the scale for the model on the right is 1 cm = 2.5 ft, the area of the model on the right is 22, or 4, times larger than the area of the model on the left.

Multiply the area of the model on the left by 4 to find the area of the model on the right.

20 sq cm × 4 = 80 sq cm

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "
