Answer:

  • 1/16
  • 720 cm²

Step-by-step explanation:

Area is the product of two dimensions.

<u>If the scale factor is 1/4, the ratio of the areas will be: </u>

  • (1/4)² = 1/16

The smaller prism has a surface are of 45 cm².

<u>The larger prism has a surface area:</u>

  • 45*16 = 720 cm²

Lets say two numbers are x and y

x+y=70-----------------------eq1

x=4y--------------------eq2

4y+y=70
5y=70
y=70/5
y=14

Find the source area of the space figure represented by the net
sergejj [24]

I assume you meant "surface area" :)

Looking at the net, it looks like if you folded it back together it would form to become a triangular prism.

To calculate the surface area of a triangular prism, you would use the formula: A = bh + 2ls + lb, where b is the base of the triangular faces, h is the height of the prism, l is the length of the prism, and s is the side length of the prism.

I attached a picture to help you see what these labels are.

Looking at the diagram you've provided, we can assume that b = 7 cm, h = 4 cm, l = 8 cm, and s = 5 cm. Substitute these into the formula.

A = bh + 2ls + lb ==> A = (7)(4) + 2(8)(5) + (8)(7)

Multiply from left to right.

28 + 80 + 56

Add.

164

The surface area of this triangular prism is A) 164 cm^2.
