Answer:
It takes 70 minutes for 9 team members (painting 60 sq ft per minute) to paint a 4200 sq ft wall.
Step-by-step explanation:
According to the situation the calculation is shown below:-
= 
= 240 sq ft each member of the team in 36 minutes
= 
= 6.67 sq ft each member of the team within 1 minute

= 60 sq ft for every 9 team members in one minute
= 
= 70 minutes (or 1 hour and 10 minutes)
Hence, the 70 minutes is taken for 9 team members
By definition, the formula for finding the area of a trapezoid is
A = [(b1 + b2) x h] / 2
Where,
b1: Base 1
b2: Base 2
h: height, or distance between bases.
Substituting we have:
A = ((5 + 4) * (2.5)) / 2
A = 11.25 feet ^ 2
Answer:
the area of the seat is:
A = 11.25 feet ^ 2
