FG = 28 meters
Step-by-step Explanation:
==>A design ABCD and its dilated photocopy EFGH.
Length of side AB = 17m
BC = 14m
DA:HE = 1:2
==>Required:
Length of side FG on the photocopy EFGH, in meters.
==>Solution:
Dilation of design ABCD would, upon transformation would produce a photocopy EFGH that is similar. Thus, ABCD ~ EFGH
Since ABCD is similar to EFGH, it means the ratio of their corresponding sides would be the same, and also have the same scale factor.
Therefore, it means DA:HE = BC:FG
Therefore, let's find length of side FG of the photocopy using the ratio1:2 that is given for DA:HE, which would also apply as the scale factor or ratio for all other corresponding sides.
Thus,
1:2 = BC:FG
1:2 = 14:FG
1/2 = 14/FG
Cross multiply to solve for FG
1×FG = 14×2
FG = 28 meters
