Step-by-step explanation:
From the figure attached,
ΔBCD and ΔACE are the similar triangles.

AB + 6 = 24
AB = 18
Option (B) will be the answer.
How much part can sally paint in an hour ?
a ÷ 7 = a/7
And what about Steve ?
a ÷ 9 = a/9
Where, a is the total area of the room.
So, let the time taken by both of them to paint the room together be 't'
So,
t(a/7 + a/9) = a
t(9a/63 + 7a/63) = a
t(16a/63) = a
t = 63/16 ≈ 4 hr
