Answer:
3/8 sq. units
Step-by-step explanation:
The formula for area for a trapezoid is
Area = (1/2)*(base1+base2)*height
Area = (1/2)*(1/2 + 1/4) * 1
Area = (1/2)*(2/4 + 1/4)
Area = (1/2)*(3/4)
Area = 3/8 sq. units
Answer:
16,080 km.
Step-by-step explanation:
We want the total number of kilometers in one year.
so
4 weeks /month.
for Work: 9 months in the year 60 km/day 5 days/week
Family Visit : 720 km for 4 times a year
Personal: 200 km / month
Work total = 60 km/day * 5 days/week * 4week/month * 9 months
WorkTotal= 60*5*4*9 = 10,800 km
FamilyTotal= 4*720 = 2880 km
Personal = 200*12 = 2400 km
Total = 10,800 + 2880 + 2400 = 16,080 km
