Question

Rectangle ABCD is placed on a grid as shown.

Which is the closest to the length of diagonal ?

a. 10.0
b. 11.7
c. 8.0
d. 11.3

Answer 1

The answer is B

11.7

Explanation:

distance between A and B

3--3=3+3=6

Distance between B and C

5--5=5+5=10

Length of diagonal²=distance between A and B²+distance between B and C ²

L²=6²+10²

L²=36+100

L²=136

take the square root of both sides

√L²=√136

L=11.7
