05.07) the net of a pyramid is shown below: the net of a square based pyramid, with bases labeled 7 inches and the height of the triangle labeled 14 inches. the surface area of the solid is square inches. numerical answers expected!

 245

Step-by-step explanation:

first you have to 7 for the square which = 14

then after that you do 1/2 b x h = 1/2  7 x 14= 3.5 x 14= 49 but then you have 4 triangles so 49 x 4=196.     Then  49 + 196= 245  

245

Step-by-step explanation:

You can find the Surface Area of a figure by adding up the areas of each shape.

First you have to find the area of the base.

7×7 = 49

Then you can find the area of the 4 triangles that complete the pyramid.

Formula for area of a triangle: (one half of base times height)

Since all the triangles are the same, you only have to calculate that once.

Now you just add everything together, and that's your surface area.

Please mark if it helped you out!~

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8

hope this
