Giveb that the two figures are similar, the scale factor of WBE to PYM will be given by:
scale factor=(length of one side of WBE)/(length pf one side of PMY)
taking length WB in WBE and corresponding length PY in PYM we shall have:
WB=21 in
PY=15 in
therefore the scale factor of WBE to PYM is:
scale factor=21/15
=7/5
=1.4
