Answer:
1/5 or 20%
Step-by-step explanation:
The total number of paintings is 60.
60 = x (x − 2) + x + 2x + 8 + 10
60 = x² − 2x + x + 2x + 18
0 = x² + x − 42
0 = (x + 7) (x − 6)
x = -7 or 6
Since x can't be negative, x = 6. So the number of paintings from the 20th century is 6 (6 − 2) + 6 = 30.
The number of paintings that are both British and from the 20th century is 6.
So the probability that a painting from the 20th century is also British is 6/30 = 1/5, or 20%.

Answer:</h3>
12 units²
<h3>
Step-by-step explanation:</h3>
Counting half-squares around the perimeter of the rectangle, we find there are 10. Counting full squares inside the rectangle, we find there are 7. Then the total area is
... (1/2)·10 +7 = 12 square units
_____
<em>Alternate calculation</em>
The long side is the hypotenuse of a right triangle with legs 3, so has length 3√2. The short side is the hypotenuse of a right triangle with legs 2, so has length 2√2. The area is the product of these lengths, so is ...
.. area = (3√2)(2√2) = 6(√2)² = 6·2 = 12 . . . square units
