Answer:
<h2>231cm²</h2>
Step-by-step explanation:
First, let's find the surface area of both the triangles
5x3=15
So, the surface area of the triangles is 15 sq.cm
Now, let's find the surface area of the base (large rectangle in the middle)
12x8=?
10x8=80
2x8=16
80+16=96
12x8=96
So, the surface area of the base, is 96sq.cm
Now, let's find the surface area of both of the side rectangles
12x5=60
60x2=120
So, the surface area of the two side rectangles is 120sq.cm
Now, let's find the total surface area by adding all of our answers.
120+96=216
216+15=231
<h2>
So hence, the surface area of this net is 231cm²</h2>

Answer:
-1/2
Step-by-step explanation:
Given:

Find the common denominator for the fractions, which is 6. Rewrite 1/3 as 2/6.

Combine like terms.

Simplify.
-0.5x = 1/4
Divide both sides by -0.5.
x = -1/2 = -0.5
