Answer:

36⁄125 or if we are talking about the lowest term it is 9 /3125


Step-by-step explanation:

Step 1: 0.288 = 288⁄1000  

Step 2: Simplify 288⁄1000 = 36⁄125 Percent" or "%" means "out of 100" or "per 100",



<em>Or for the lowest term:</em>

0.288

1000

100000

.

We can now reduce the fraction as:

100000

⇒

Find the area. Round to the nearest tenth.
olga_2 [115]

Answer:

Step-by-step explanation:

The area of a triangle is

A=\frac{1}{2}bh and we have the base (12m) and we need to find the height. Using Pythagorean's Theorem:

6^2=4^2+h^2\\36=16+h^2\\20=h^2\\h=2\sqrt{5}

That's the height that we will sub into the area formula:

A=\frac{1}{2}(12)(2\sqrt{5})\\A=12\sqrt{5}\\A=26.8
