the area of an equaliteral Triangle is
16_/3 Find Find the length of each side and perimeter of the triangle.
Answers
♦ The length of each side of the equilateral triangle is 8 cm
♦ The Perimeter of the equilateral triangle is 24 cm
Given :-
• The area of an equilateral triangle is 16√3 cm².
To find :-
• The length of each side of the triangle.
• The Perimeter of the triangle.
Solution :-
Let the each side of an equilateral triangle be a cm
We know that
Area of an equilateral triangle is
(√3/4) a² sq.units
Therefore, (√3/4) a² = 16√3
=> a² = 16√3×(4/√3)
=> a² = (16×√3×4)/√3
=> a² = 16×4
=> a² = 64
=> a = ±√64
=> a = ±8
=> a = 8 cm
Since, The length of the side can't be negative.
Therefore, The length of the each side is 8 cm
We know that
The Perimeter of an equilateral triangle is 3a units
Perimeter of the given equilateral triangle
= 3(8) cm
= 24 cm
Answer :-
♦ The length of each side of the equilateral triangle is 8 cm
♦ The Perimeter of the equilateral triangle is 24 cm
Used formulae:-
♦ Area of an equilateral triangle is (√3/4) a² sq.units
♦ The Perimeter of an equilateral triangle is 3a units
- a = side
GIVEN :-
the area of an equaliteral Triangle is
16√3
TO FIND :-
- Find the length of each side and perimeter of the triangle = ?
SOLUTION :-
Given area of equilateral triangle is 16√3cm², Now we know that area of equilateral triangle
is √3/4 (side)²
√3/4 (side)² = 16√3
side² = 4 × 16
side² = 64
side = 8cm
Now perimeter of an equilateral triangle is given by 3 (side)
Perimeter of an equilateral triangle = 3(8)cm
= 24cm
Perimeter of an equilateral triangle
is 24 cm.
