Answer:
1 3/25 m2.
Step-by-step explanation:
Let the portion of the wall painted by Jiaqi, Gwen and Patricia be denoted as X, Y and Z respectively.
Jiaqi (X):
= 4/7
Gwen (Y):
=1/2*(1 - 4/7)
= 1/2*(3/7).
= 3/14.
Patricia (Z):
=1/2*(1 - 4/7)
= 1/2*(3/7).
= 3/14.
Area of the wall painted:
Let the area of the wall painted by Gwen and Patricia be Y + Z.
The area painted by Jiaqi = 2/5 + Y + Z
Therefore,
4/7 = 2/5 + Y + Z
The ratio of portions painted by:
Jiaqi : Gwen : Patricia : Total
4 : 3/2 : 3/2 : 7
Multiple by 2,
8 : 3 : 3 : 14
= (X - (Y + Z))
8 – 3 = 5,
but, 5 units = 2/5,
Total units, 14 units = 28/25
= 1 3/25
1 3/25 m2.
