Answer 2

Solution :-

Given ,

• Side of triangle = 10√3 cm
• Type of triangle :- Equilateral triangle

We need to find ,

• Area of triangle = ?

As we know that ,

Area of Equilateral triangle = √3/4 a²

Where , ‘a’ is side of triangle = 10√3 cm

⇒ Area of ∆ = √3/4 × ( 10√3 )²

⇒ Area of ∆ = √3/4 × [ 100(3) ]

⇒ Area of ∆ = √3/4 × 300

⇒ Area of ∆ = √3 × 75

⇒ Area of ∆ = 75√3 cm²

Hence , area of the Equilateral ∆ = 75√3 cm²

More information :-

• Area of ∆ = 1/2 × base × height
• Area of square = side²
• Area of rectangle = l × b
• Perimeter of rectangle = 2(l + b)
• Perimeter of square = 4 × side
