Step-by-step explanation:
This a 30° 60° 90° special triangle and the side lengths would be 4 4√3 8
To calculate the primeter of a triangle we add all three side lengths together therefore the perimeter of this triangle is 4 + 4√3 + 8 = 12 + 4√3 or 18.9 (because 4√3 is = 6.9 approximately)
We calculate area of a triangle by multiplying height to the base and that divided by two
The height given here is 4√3 and base is 4
4√3 × 4 ÷ 2 = 8√3 ft^2
