Answer:
4√3 cm^2
Step-by-step explanation:
30 60 90 right triangle
The ratio of short leg : long leg : hypo. = x : x√3 :2x
Given Hypo BC = 4 = 2 * 2
so Long leg = 2√3
Area of ABC = 1/2 (b)(h)
= 1/2 (4)(2√3)
= 4√3
Answer
4√3 cm^2
Perimeter = 3 x 4 = 12 cm (you asked from other, so I answered for you as well)
