Answer:
<h2>Island A, B and C has 10, 5 and 7 houses respectively.</h2>
Step-by-step explanation:
Let, the three islands A, B and C has a, b and c houses respectively.
According to the question, a + b = 15; a + c = 17; b + c = 12; a + b + c = 22.
Adding [ a + b = 15; a + c = 17]-these two, we get, 
.
Now, 
.
.
W + 8 = -4 - 6w / + 6w;
7w + 8 = - 4 / -8;
7w = -12 /÷7
w = -12/7 is the solution of the equation.
We verify: -12/7 + 8 = -4 - 6 x ( -12/7 );
Then, -12/7 + 56/7 = -28/7 + 72/7;
44/7 = 44/7 ( TRUE );
Area will be length*width
Area = 3*6 = 18 feet^2
