The perimeter of a rectangle is 48cm. if the length is 16 cm, find the measure of the width in centimeters

The width is 8 cm. There are 2 lengths, one on each side, so there's 32 cm. 48-32=16. There are 2 widths, so 16/2= 8 for width.

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 "

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
