Area of a triangle = (h × b) ÷ 2, where h is height and b is the base.
7.1 × 28 = 198.8
198.8 ÷ 2 = 99.4
The area of this triangle is 99.4 yd²
Answer:
99.4 yd²
Step-by-step explanation:
The area (A) of a triangle is calculated using the formula
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
here b = 28 and h = 7.1, hence
A = 0.5 × 28 × 7.1 = 99.4 yd²
