Find the area of an equilateral triangle if its perimeter is 18 ft
24 feet (8 x 3)
The perimeter outside a rectangle with an area of 800 square feet can vary from 113.137... feet to 802 feet. In a triangle, it can vary anywhere from 80 + 40√2 to 2√800 + 2(√800√2). You can never derive the exact perimeter of a figure from an area alone.
The area of a square with a perimeter of 22.33 feet is: 31.16 square feet.
The perimeter is 18 feet.
The perimeter will be four feet.
An equilateral triangle that has a perimeter of 57 feet has three equal sides of 19 feet.
4 feet
It works out as 22.335 feet rounded to three decimal places
Perimeter = 3*8 = 24 feet
The area is 9.2376 square feet.
8 feet x 3 sides = 24 foot perimeter.
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.

Equilateral triangles have all sides the same length, and to get the perimeter, you add all the side lengths. 15+15+15=45
