Answer:
A = (x + 7)(x + 9)
Step-by-step explanation:
Let the width w = x
then length l = w + 4 = x + 4
Area = length x width
= x(x+4)
Then the the width is increased by 7 units and the length increased by 5 units.
w = x + 7
l = (x + 4) + 5 =x + 9
A = (x + 7)(x + 9)

Answer:
4.8 hours
Step-by-step explanation:
6 hours = 360 minutes (6x60)
360/5 = 72 (minutes per person worked)
72/2= 36 (person working at half productivity)
36x 8= 288 (total minutes of 8 people working at half productivity)
288/60= 4.8 (cover minutes back to hours)
