In the figure, BCND is a rectangle and CGNR is a rhombus. The area of BCND is 90 and BC = 10. What is 3GR?

PIT_PIT [208]

Answer:

$3GR=27$

Step-by-step explanation:

Since area of rectangle BCND is given as 90 and one of its side is 10, the other side MUST be 9.

$CN*BC=90\\CN*10=90\\CN=9$

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.
