Ответ:
then the volume scale factor will be:
volume scale factor=(volume of large figure)/(volume of small figure)
Volume scale factor=250/2=125/1
linear scale factor=∛VSF=∛(125/1)=5/1
to get the are of larger figure we need area scale factor
Area scale factor=(linear scale factor)²
=(5/1)²=25/1
thus the area of larger figure will be:
25/1×13
=325 yd²
Ответ:
160:140
Step-by-step explanation:
8+7 = 15
60000/15 = 4000
4000/200=20
therfore the dimensions are 20 times the amount
8x 20 = 160
7x 20 = 140
