Answer:
777
Step-by-step explanation:
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)
Assuming they are all standardised numbers, from largest:
Number of fans attending a World Series baseball game (10,000+)
Value of a home computer (~800)
Number of buttons on a telephone (10)
Average number of cars that can fit in a home garage (2)
Answer:
284.52
Step-by-step explanation:
total area = area of semi circle + area of rectangle
area of semicircle = pi r^2 /2.
= 3.14 * (12/2) ^2 ...divided by 2
= 56.52
area of rectangle = length * breadth
= 19*12
= 228
