Answer:

The frame should be 36 + 2b + 16 + 2b

Step-by-step explanation:

To solve this question, let assign 36 in x 16 in as the dimension of the painting.

276 in^2 is the area of the framing material to be used.

Let the width of the frame around the frame be "b", thus; the dimension of the frame is 36 + 2b + 16 + 2b

Answer:

a= 20

b= 169.7

c= 29.71

Step-by-step explanation:

The formula of a triangle is (h*b)/2

a= (5*8)/2

b= to find the height, you can use the pythagorean theorem 18^2 - 6^2 = square root of 288. Which is 12root 2 or 16.97. (16.97*20)/2

c= using the pythagorean theorem- 11^2 = 7^2 - c^2 = square root 73, or 6root 2, or 8.49. (8.49* 7)/2
