Equilateral triangles have all sides the same length, and to get the perimeter, you add all the side lengths.
15+15+15=45
An equilateral triangle that has a perimeter of 57 feet has three equal sides of 19 feet.
4 feet
Perimeter = 3*8 = 24 feet
The perimeter measures 5,900 feet.
The maximum area is just under 3.9 sq feet [exactly (3/2)2*sqrt(3) sq ft] - an area that is attained by an equilateral triangle. Since the question specifies an isosceles triangle, the answer is very very slightly less than that.
Find the area of an equilateral triangle if its perimeter is 18 ft
8 feet x 3 sides = 24 foot perimeter.
24 feet (8 x 3)
An equilateral triangle that has a perimeter of 57 feet has three equal sides of 19 feet.
4 feet
Perimeter = 3*8 = 24 feet
52+52+52 156
It works out as 22.335 feet rounded to three decimal places
20ft is the perimeter.
The perimeter measures 5,900 feet.
