What is the area, in square centimeters, of the isosceles trapezoid below

A = 39.48 cm²

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₂ the parallel bases

Here h = 4.2, b₁ = 13.5, b₂ = 5.3 , then

A = × 4.2 × (13.5 + 5.3) = 2.1 × 18.8 = 39.48 cm²

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 "

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
