Answer:
The area of a rhombus is
square units.
Step-by-step explanation:
Side length of rhombus = 6 units.
Interior angle of rhombus = 120°
another Interior angle of rhombus = 180°-120° = 60°.
Draw an altitude.
In a right angled triangle



Multiply both sides by 6.

The height of the rhombus is
.
Area of a rhombus is



Therefore, the area of a rhombus is
square units.
Answer:
10.58
Step-by-step explanation:
Answer:
31.5 units²
Step-by-step explanation:
Area = ½*base*height
Height of the triangle on the grid = 9 units
Base = 7 units
Area = ½*9*7
Area = ½*63
Area = 63/2
Area = 31.5 units²
