Helllppp i will give you brainliest if you can help meeeeeeeee
Alja [10]

Answer:

20 square meters

Step-by-step explanation:

To do this continue the line of the top of the rectangle so you split the figure into a triangle and a rectangle. The dimensions of the rectangle would be 8 by 2, so 8 * 2 = 16. Next, the dimensions of the triangle would be (4 - 2) by (8 - 4) = 2 by 4. The area would then be 2 * 4 = 8/2 = 4.

All you have to do now is add those two areas together, 16 + 4 = 20 square meters.

25 percent of what is 38?
AnnyKZ [126]

Answer: 152

Step-by-step explanation:

Let the number = x.

Therefore, x*25% = 38

25% as a decimal is 0.25.

So, 0.25x = 38

We can divide both sides by 0.25:

x = 152
