The formula of a perimeter of a rectangle:
The formula of an area of a rectangle:
l - lenght
w - width
We have l = 3w and the perimeter P = 256 in. Substitute:
<em>divide both sides by 2</em>
<em>divide both sides by 4</em>
Calculate the area of a rectangle:
The triangle ABC is the half of the rectangle. Therefore the area of a triangle ABC is:
Here is my answer. I hope this is helpful.
The correct answer is Choice C.
The ratio given is 2 to 3. All of the choices give the total of 15 glass as needed. However, only choice C is also in the ratio of 2 to 3.
6/9 can be reduced to the fraction 2/3 by dividing by 3.
4.80 = 100%
x = 55%
Cross Multiply
100 * x = 55 * 4.80
100x = 264
x = <u>264</u>
100
x = 2.64
Solution: $2.64
