Answer:

45 minutes

Step-by-step explanation:

Assume task completed in total x hours

$\frac{x}{10} + \frac{3}{8} + \frac{3}{12} = 1 \\ 12x + 45 + 30 = 120 \\ 12x = 45 \\ x = \frac{15}{4} = 3 \frac{3}{4}$

So q will take 45 more minutes

L=w+2 and 2w+2l=40

Substitute length for w+2 in perimeter formula.

2w+2(w+2)=40
2w+2w+4=40
4w+4=40
4w=36
w=9

l=w+2
l=9+2
l=11

a=lw=11*9=99 meters
