Answer: Equation: 0.5*30*b = 210
Base length: 14
Step-by-step explanation: The formula of the area of a triangle is 1/2*b*h, so we can use that and the information given to make a formula then solve.
Answer:
A ≈ 5.6
Step-by-step explanation:
The area (A) of the triangle is calculated as
A =
× PQ × PR × sin P
= 0.5 × 5.2 × 2.8 × sin50°
≈ 5.6 ( to 1 dec. place )
