Because 1 * 21 = 3 * 7 ( 21 = 21 ) , 1/3&7/21 form a proportion.
option (D) 28 √6 is the answer
Explanation :
p =3√6 + 2√24 + 7√54
3√6 + 2√2×2×6+ 7√3×3×6
3√6 +2 ×2√6 + 7 ×3√6
3√6 +4√6 + 21√6
28√6
Answer:
A = 120, P = 55
Step-by-step explanation:
Triangle
Area = (bh)/2
A = (20x12)/2
A =240/2
A = 120
Perimeter = a + b + c
to find c, use a^2 +b^2 = c^2
20^2 + 12^2 = c^2
400 + 144 = c^2
544 = c^2
c = about 23
20 + 12 + 23 = 55
