A triangular window has an area of 600 in 2. The base of the window is three times its height. What is the length of the base of the window?

Base = 60inches

Step-by-step explanation:

We don't know the height of the triangle, so let's call it x.

The base is three times the height. So it will be 3x.

The area is 600 square inches. And the Area of a triangle is

1/2 × base × height

600 = 1/2 (3x)(x)

times both sides by2

2•600 = 2•1/2•3x^2

1200 = 3x^2

divide by 3.

1200/3 = 3x^2 /3

400 = x^2

sqrt both sides.

sqrt(400) = sqrt(x^2)

20 = x

x is the height. The height is 20 inches.

The base is 3x= 3(20) = 60inches

gregory's graph is incorrect because it shows 2 inches of growth for each week when it should show 0.75 inches of growth each week.

yes
