Answer:
area = 15 in²
Step-by-step explanation:
The area (A) of a triangle is calculated using the formula
A =
bh ( b is the base and h the height )
here b = 10 and h = 3, hence
A =
×10 × 3 = 15 in²

Answer:
Step-by-step explanation:
<u>As per diagram we have:</u>
<u>As per 30° right triangle property:</u>
- CD = √3×CB/2 = 3√3 ≈ 5.2 cm
- and
- AC = 2CD = 2×5.2 = 10.4 cm
<u>Area of triangle:</u>
- A = 1/2bh
- A = 1/2CB*AC
- A = 1/2*5.2*10.4 ≈ 27 cm²
