<h3>Answer: 10</h3>

Explanation:

"percent" means "per one hundred". Think "cent" as in "100 cents in a dollar". That's one way to remember.

So when we say something like 2%, we mean 2 out of 100 leading to the fraction 2/100 = 0.02

The same applies for 4.8% turning into 4.8/100 = 0.048

A quick shortcut without the use of a calculator has us move the decimal point 2 spots to the left to go from 4.8% to 0.048

-------------

After converting 4.8% to 0.048, we then multiply this by 200

200*(0.048) = 9.6

this value rounds to 10 which is the answer

Divide the figure into a triangle on the left and a rectangle on the right. You know the side lengths of the rectangle are 3 x 10, so multiply to get the area of the rectangle. Next, find the area of the triangle. The area of a triangle is given by 1/2bh, where b is the base and h is the height. Because you know the short side of the rectangle is 3, subtract 3 from 5 to get the base of the triangle. then multiply that by 10, the height, and divide by 2 to get the area of the triangle. Then just add up the area of the triangle and the area of the rectangle to get your answer :)
