Extend the vertical line on the right so it divides the figure into a rectangle and a triangle.

The rectangle is 5 in high and 7 in wide, so has an area of (5 in)*(7 in) = 35 in^2.

The triangle is (5 in -3 in) = 2 in high and (12 in -7 in) = 5 in wide, so has an area of
.. (1/2)*(2 in)*(5 in) = 5 in^2

The total area of rectangle and triangle is 35 in^2 +5 in^2 = 40 in^2.

<h3>What is a ratio?</h3>

In mathematics, ratios are used to determine the relationship between two numbers it indicates how many times is one number to another number.

<h3 />

The given ratios are:-

Mixture A = $\dfrac{5}{12} = 0.41$

Mixture B = $\dfrac{6}{6}= 1$

Mixture C = $\dfrac{4}{12}= 0.33$

Mixture B = $\dfrac{5}{6}=0.83$

Here the ratio of mixture B is the highest among all the options available.

Therefore the correct answer is option B which is mixture B will have the highest ratio of blue paint.

how do I find the area of an equilateral triangle given the perimeter of 60 and the height of 17.3 cm?

guajiro [1.7K]

If perimeter is 60 so the side is 60 ÷ 3 = 20

Now we can apply the area formula for triangles;

$A=\frac{1}{2}.b.h\\
\\
A=\frac{1}{2}.20.17.3=10.17.3=173 \ cm^2$
