Surface Area, eh?

So, to solve this, you need to understand that Surface Area is just the added areas of the faces that make up the figure!

So, we just find all the areas of the faces, add them together, and there you go!

Let's solve!

SA=(14*10)+2(25*10)+2(\frac{24*14}{2})

So, there is our equation!

Wondering how I got it? Follow along!

I got (14*10) with that rectangle on the end of that rectangular prism, simple, as the area is just the multiplication of the lengths of the sides.

Now, same thing with 2(25*10), but why did I multiply by 2? It is because there is an identical face on the other side.

I also got 2(24*14/2) with the area of a triangle formula as the altitude is 24m. if you don't know what that is, might want to check google!(I also multiplied it by 2 because there was another identical face on the other side).

So, now that you understand where I am coming from, let us solve!

SA=140+500+336\\SA=976

More accurately, it is 976 m^2!

So, there you have it!

If you do need more help, check online! It is the greatest source of information that we have developed!

Adios!

Angle 3 and angle 4 are supplementary angles. Angle 3 is 88. What is the measure of angle 4?
Mademuasel [1]
Since angles 3 and 4 are supplementary, they add up to 180 degrees.

Angle 3 is 88 degrees.

To get the measure of the last angle, let's subtract 88 from 180.

180 - 88 = 92

Thus, Angle 4 has a measure of 92 degrees.

Have an awesome day! :)

denis23 [38]
Unit rate refers to how much the buyer paid per unit. Let’s do the math:

$2.52 for 4.5 pounds of potatoes
Divide $2.52 by 4.5
The shopper paid 56 cents per pound of potatoes.
Now $7.75 spent for 2.5 pounds of broccoli.
Divide $7.75 by 2.5.
The shopper paid $3.10 for each pound of broccoli.
Last $2.45 for 2.5 pounds of pears.
The shopper will spend 98 cents per pounds of pears.
