I’m pretty sure the answer is B.
Answer:
d
Step-by-step explanation:
Given the x and y are in direct variation then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 12 when x = 4, that is
12 = 4k ( divide both sides by 4 )
3 = k
y = 3k ← equation of variation
When x = 20 , then
y = 3 × 20 = 60 → d

Total area = 12 + 18 = 30cm²
Factor the numerator and denominator and cancel the common factors.
The answer would be 1/4
