D is correct because y on I doesn't equal y on II.
Answer: AB = 30cm, BD = 16cm, CD = 30 cm, AC = 16 cm
Diagram should be the same thing, except doubled the size of the original.
Explanation: Just multiply each side by the scale factor.
600 is the answer. 600x10 is 6000
Answer:
60cm^2
Step-by-step explanation:
We assume that is a circumscribing quadrilateral, rather than one that is circumscribed. It is also called a "tangential quadrilateral" and its area is ...
K = sr
where s is the semi-perimeter, the sum of opposite sides, and r is the radius of the incircle.
K = (12 cm) (5cm) = 60 cm²
_____
A quadrilateral can only be tangential if pairs of opposite sides add to the same length. Hence the given sum is the semiperimeter.
