Find the area of the triangle SHOW WORK

kykrilka [37]

Answer:

The area of triangle is 1263.6 mm².

This is an Equilateral triangle.

Step-by-step explanation:

Given that the area of triangle formula is A = 1/2×base×height. So you have to substitute the values into the formula :

$area = \frac{1}{2} \times base \times height$

Let base = 54mm,

Let height = 46.8mm,

$area = \frac{1}{2} \times 54 \times 46.8$

$area = \frac{1}{2} \times 2527.2$

$area = 1263.6 \: {mm}^{2}$

This is the Equilateral triangle because all sides of the triangle are equal.

Solve for R 3 r + 4 ---------- = 5 2 r = ?

lakkis [162]

To find r, first write out the equation:
$\frac{3r+4}{2} =5$
Next, multiply both sides by 2:
$3r+4=10$
Now, subtract both sides by 4:
$3r = 6$
Divide both sides by 3:
$r=2$

The answer to this problem is r = 2. Hope this helps and have a phenomenal day!
