Question

AABC and AXYZ are similar, and if AB =11 cm, XY= 7 cm and BC = 22 cm, then YZ =
​

Answer 1

Answer:

First find the scale factor:

Since BC = 10 and YZ = 20, the scale factor is found by dividing YZ by BC

Scale factor =

10

20

=2

Now use the same scale factor to find the length of XZ:

XZ = 2 x 12 = 24
