Answer:
A
Step-by-step explanation:
18 * 18 = 324
19 * 19 = 361
The area of the frame is 357 sq in. which is between 324 sq in. and 361 sq in., so the side is between 18 in. and 19 in.
Answer: A.

Answer:
Step-by-step explanation:
Answer: 32/1 = 256/8 and 1/4=2/8 so, 5/8 + 2/8 = 7/8. 256/8 - 7/8 = 249/8

Answer:
Step-by-step explanation:
In order to find the surface area of a 3-dimensional figure, one must find the 2-dimensional area of all of its faces, then add up the values to find the surface area of the entire figure. The given prism is drawn out in the form of a net, thus, it is rather easy to find the area of each face, and add up the area to find the surface area.
The lateral surface area refers to the surface area of a figure, not including the base of the figure. In this case, the base is the largest rectangle: the one with the dimensions of the following length
Use the following formulas to find the surface area of each face:
Rectangle:
Triangle:
Add up all of these values to find the total surface area:
