Step-by-step explanation:
We need to find the height of the triangle first.
Height=>sin(60°)=h/3 but sin(60°)=√3/2
h=3×√3/2=3√3/2
Area=½×base×height
A=½×3×3√3/2
A=9√3/4
Answer is option A
Answer:
Step-by-step explanation:
Area of rectangle = length * width
Area of rectangle = 55x⁶ + 22x⁴
= 5*11*x⁶ + 2 *11*x⁴
= 11x⁴*(5x² + 2)
width = 11x⁴
So, length = 5x² + 2
