In the figure, BCND is a rectangle and CGNR is a rhombus. The area of BCND is 90 and BC = 10. What is 3GR?
1 answer:
Answer:
Step-by-step explanation:
<u>Since area of rectangle BCND is given as 90 and one of its side is 10, the other side MUST be 9.</u>
<u>
</u>
In Rhombus CGNR, CN and GR are congruent (property of Rhombus). Hence GR = 9 as well.
Thus 3GR = 3(9) = 27
First answer choice is right.
