Answer:
2 units²
Explanation:
The diameter is 4 units.
The radius is 4/2 = 2 units.
The two legs of the triangle are a measure of 2 units or just the radius length.
Area of triangle = bh × 1/2
2 × 2 × 1/2
4/2 = 2
Area = 2
Givens
The leg and the height of the right angle triangle are both radii of the semi circle.
The diameter of the semicircle is 4
Solution
radius = diameter /2
radius = 4/2
radius = 2
Area = 1/2 * b * h
b = 2
h = 2
Area = 1/2 * 2 * 2
