Answer:

Step-by-step explanation:
we know that
An <u><em>equilateral triangle</em></u> has three equal sides and three equal interior angles (each interior angle measure 60 degrees)
so
The perimeter is equal to

where
b is the length side of the equilateral triangle
we have

substitute

solve for b

Find the area
The formula of area applying the law of sines is equal to

substitute the value of b

Answer:
The Answer is: Perimeter = 39.12
Step-by-step explanation:
Given: area is 56.96 m^2
Given: length is 16m.
Find Width.
Equation:
Length x Width = Area
Solve for Width, w.
16 x w = 56.96
w = 56.96/16 = 3.56.
Perimeter all the sides added together:
P= 2l + 2w 
= 2(16) + 2(3.56)
= 32 + 7.12
= 39.12 m, perimeter
