Answer:
Area = 27√3/4 square units
Step-by-step explanation:
Since the shape is an equilateral triangle, all the sides will be equal
Area of the triangle = 1/2 * base * height
Get the height
(3√3)² = h²+(3√3/2)²
27 = h² + (27/4)
h²= 27 - 27/4
h² = 27 - 6.75
h² = 20.25
h = √2025/100
h = 45/10
Area = 1/2 * 3√3 * 45/10
Area = 135√3/20
Area = 27√3/4 square units
