Apicture inside a frame is 2 inches longer than it is wide. the picture is in a frame that has a width of 3 inches on each side of the picture. if the area of the picture, including the frame, is 195 inches^2, find the dimensions of the frame.

The dimensions of the frame are 15 in x 13 in

Step-by-step explanation:

Let

x ----> the length of the picture

y ----> the width of the picture

we know that

-----> equation A

The area of the picture, including the frame is

so

----> equation B

substitute equation A in equation B

solve for y

solve the quadratic equation by graphing

The solution is y=7 in

see the attached figure

Find the value of x

Find the dimensions of the frame

therefore

The dimensions of the frame are 15 in x 13 in

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 "
