get a common denominator between 6,12,7,2 = 84
Step-by-step explanation:
We will get the areas of each one of the given triangles:
7) A = 12.69 mm²
8) A = 19.21 in²
9) A = 16.81 yd²
<h3>How to get the area of the given triangles?</h3>
7) First, we have an equilateral triangle, where all the sides measure 5.4mm
For an equilateral triangle of side length S, the area is:
In this case, S = 5.4 mm, replacing we get:
8) Now we have two equal sides and one different. The general area of a triangle of base B and height H is:
A = B*H/2.
In this case, the base measures 3.4 in.
To get the height, let's divide the triangle into two right triangles, such that one cathetus is 3.4in/2 = 1.7 in.
The hypotenuse measures 5.9 in
And the other cathetus is the height of the triangle.
Then, by using the Pythagorean theorem, we see that the height is:
Then the area of this triangle is:
9) Here the base measures 8.2 yds, and the height 4.1 yds, so the area is just:
