Answer:
24179 square inches
Step-by-step explanation:
In ΔRST, r = 620 inches, s = 840 inches and t=230 inches. Find the area of ΔRST to the nearest square inch.
We use the formula
Heron's formula = √s(s - a)(s - b)(s - c)
Where s = a + b + c/2
Solving for s
s = 620 + 840 + 230/2
s = 845
Solving for the area of the triangle
= √845 × (845 - 620) × (845 - 840) × (845 - 230)
= √584634375
= 24,179.213696893 square inches
Approximately = 24179 square inches
Answer:
a) m = 3 b = 1/5
