Step-by-step explanation:
Area of trapezium = 1/2(a+b)h
= 1/2(10+24)12
= 1/2×34×12
= 204 square units
Answer:
Option 3
Step-by-step explanation:
Paint required is equal to the surface area of the wall
Area = 15.2 × 23
= 349.6 ft²
Answer:
78,732
Step-by-step explanation:
a_1 = 4
a_2 = 12
a_2/a_1 = 12/4 = 3
a_1 = 4
a_2 = 4 * 3 = 4 * 3^1 = 12
a_3 = 4 * 3 * 3 = 4 * 3^2 = 36
a_n = 4 * 3^(n - 1)
For n = 10:
a_10 = 4 * 3^(10 - 1) = 4 * 3^9 = 4 * 19,683 = 78,732
It'd be too hard to comment the answer but here, lemme know if you aren't able to se it
