The four folded parts of an envelope are opened up to create this figure. what is the surface area of one side of the unfolded envelope? a. 25 square centimeters b. 37 square centimeters c. 50 square centimeters d. 64 square centimeters

Option C. 50 square centimeters

Step-by-step explanation:

we know that

The surface area is equal to the area of four triangles plus the area of rectangle

so

C

Step-by-step explanation:

The total area comprises of the rectangle (area is base * height) and the 4 triangles (area = 1/2 * base * height).

Area of rectangle = 6 * 4 = 24

Area of top triangle = 1/2 * 6 * 3 = 9

Area of bottom triangle = 1/2 * 6 * 3 = 9

Area of rightside triangle = 1/2 * 4 * 2 = 4

Area of leftside triangle = 1/2 * 4 * 2 = 4

Let's add them up and find the correct

Area = 24 + 9 + 9 + 4 + 4 = 50

it could 14.28 but if its not that one then it has to be the 17 one. hope this ! : )

step-by-step explanation:

answer is : muchas/tipicas

have a nice day!
