Answer:
B. 152 cm²
Step-by-step explanation:
To find the surface area using a net, do this:
Take apart the figure. We see that there are three rectangles and two triangles. Find the area of each () and then add the values together:
The first rectangle on the left is the same as the one on the right.
Two measures are 40 cm².
The middle rectangle is:
48 cm²
The formula for the area of a triangle is :
The area of the two triangles is 12 cm².
Now add the values:
The area of the figure is 152 cm².

100
10 + 45*2
10 + 90
13.50=1.50+.6x
13.50=1.50+ .6x
12=.6x
20=x
x = 5/-6 + (√13)/-6
x = 5/-6 -(√13)/-6
2x^2 = -x^2 - 5x - 1. Subtract 2x^2 from both sides.
-3x^2 - 5x - 1. Do the quadratic formula.
That gives you:
-5/6 ± (√13)/-6.
