Answer:
Area rhombus = 110
Step-by-step explanation:
The diagonals of a rhombus intersect at right angles.
They bisect each other.
So the diagonals form 4 right angle triangles whose legs are 1/2 of each of them.
Leg of 1 triangle = 1/2 * 10 = 5
Other leg of 1 triangle = 1/2 * 22 = 11
Area of 1 triangle = (1/2 ) * 5 * 11 = 1/2 * 55 = 27.5
Area of all 4 triangles = 4 * 27.5
Area of all 4 triangles = 110
Area of rhombus = 110
