Answer:
300
Step-by-step explanation:
area=20*15=300
Answer: 700m^2
length = 20m
breadth= 15m
so we use lateral surface area = 2(L+B) H
area of hall = 2(20+15)10
2×35×10 = 700m^2 ans
b
given s(t) = t³ - 5t then
v(t) = s'(t) = 3t² - 5 and
v(3) = 3(3)² - 5 = 22 m / s, and
a(t) = v'(t) = 6t, then
a(3) = 6 × 3 = 18 m / s²
