Number 4 is B and number 5 is A (sorry if it’s wrong)
Answer:
D
Step-by-step explanation:
The quadrilateral have equal opposite sides, for example:
Then, (4x + 6) must be equal to (7x - 3), and (4y - 3) is equal to (3y + 1), therefore

We can solve that equation for x

Hence, x = 3. Now let's solve the other equation

Then the value of y is 4.
Final answers:
x = 3
y = 4
It should be 5 cm should be the numerator
The correct answer is 100
Because 5*20=. 100
100\1= 100
