Answer:

<h2>120 square meters</h2>

Step-by-step explanation:

To find the SA of 2 Triangles, we will use the formula... B x H, and the Base and Height is going to be the dimensions of just 1 triangle, but it's going to give the answer for 2 triangles, in this shape, we have 2 triangles.

SA = B x H

= 6 x 4

= 24

24 square meters for both of the triangles

Now, let's find the SA of the rectangle on the bottom...

SA = L x W

= 6 x 6

= 36

36 square meters for 1 of the 3 rectangular parts, the one on the bottom

Now, lets find the SA of the 2 rectangles on the top. We'll use the dimensions of 1 rectangle and find the answer for 2 answers by using the formula...

SA = L x W x 2

= 6 x 5 x 2

= 30 x 2

= 60

60 square meters for the 2 rectangles on the top.

Now, we have to add all of our answers.

24 + 36 + 60 = 120 square meters

<h2>Hence, the SA (surface area) of this shape is 120 square meters.</h2>

I need help with #10!
DiKsa [7]

Answer: 6 years old.

Step-by-step explanation:

For this exercise let "x" represents your present age.

According to the information provided in the exercise, you know that  In three years, Chad will be three times your present age.

Then, your age in three years can be represented with the following expression:

x+3

Knowing at that time Chad's age will be three times yours and you will be half as old as old as Chad, you can write the following equation to represent this situation:

x+3=\frac{3x}{2}

Therefore, the final step is to solve for "x" in order to find its value.

You get that this is:

2(x+3)=3x\\\\2x+6=3x\\\\6=3x-2x\\\\x=6
