Answer 1

Answer:

30.9 square centimeters

Step-by-step explanation:

3 * 1/2(3)(6) + 1/2(3)(2.6) = 30.9

Answer 2

Answer:

30.9 cm²

Step-by-step explanation:

To find the surface area of this figure, we find the area of the base and the 3 identical sides.

The base is split into two identical right triangles. Let's find the area of one and multiply by two.

Half of 3: 1.5

$1.5\cdot2.6=3.9\\3.9\div2=1.95$

There are two right triangles:

$1.95\cdot2=3.9$

The area of one of the sides will be the same thing, except the height is 6.

$1.5\cdot6=9\\9\div2=4.5\\4.5\cdot2=9$

There are 3 sides identical to this one:

$9\cdot3=27$.

Add 27 and 3.9:

$27+3.9=30.9$

Hope this helped!
