Answer:
A = 173 m²
Step-by-step explanation:
P = 60m = 3L => L = 60 : 3 = 20 m
A = L×h/2 = 20m×17.3m/2 = 10m×17.3m = 173 m²
Answer:
The area of the triangle is 173 squared meters.
Step-by-step explanation:
An equilateral triangle has all sides equal to each other.
Finding the length of each side of the triangle.
Like I said before, in an equilateral triangle all the sides are equal. The perimeter of a triangle is every side added together. Since each side is equal, you will divide 60 (the perimeter) by 3 (the number of sides).
[tex]\frac{60}{3} = 20[/tex]
Each side is equal to 20 meters.
Finding the area of the triangle
To find the area of a triangle you need the formula: [tex]A = \frac{1}{2} bh[/tex]
A is the area, b is the base, and h is the height.
b = 20
h = 17.3
[tex]A=\frac{1}{2} (20)(17.3)[/tex] Multiply what is in the parenthesis first
[tex]A = \frac{1}{2} (346)[/tex] Multiply 346 by 1
[tex]A = \frac{346}{2}[/tex] Divide 346 by 2
[tex]A = 173[/tex]
