Step-by-step explanation:
SF of KP to KN = 4
If LM = 32, then we would have to divide 32 by 4 in order to get the missing length of KL.
32 ÷ 4 = 8
Length of KL = 8
Length of LM = 32
Length of KM = 32 + 8 = <u>4</u><u>0</u>
Question number b is the correct one
Answer:
The enlarged height of the photo must be 682 inches
Step-by-step explanation:
A customer wants to enlarge the image by 22 times
Hence, the scale factor = +22
Now, the current height of the photo = 31 inches
Therefore, to find the enlarged height : we need to multiply the scale factor of the required image by the current height of the photo.
Hence, Enlarged Height = 22 × 31
= 682 inches
So, The enlarged height of the photo must be 682 inches
