An equilateral triangle has a perimeter of 48 cm. What is the area?
KiRa [710]

Answer:

A=64\sqrt{3}\ cm^2

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

P=3b

where

b is the length side of the equilateral triangle

we have

P=48\ cm

substitute

48=3b

solve for b

b=48/3\\b=16\ cm

Find the area

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

A=\frac{1}{2}b^2sin(60^o)

substitute the value of b

A=\frac{1}{2}(16)^2sin(60^o)

sin(60^o)=\frac{\sqrt{3}}{2}

A=\frac{1}{2}(16)^2(\frac{\sqrt{3}}{2})

A=64\sqrt{3}\ cm^2

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
