Answer:


Step-by-step explanation:
Given



Required
The size of
of height 
First, we calculate the width using the following equivalent ratios

Express as fraction

Solve for x


Hence:
--- approximated
So, we have:


The size (diagonal) is then calculated using:




--- approximated
Part a
60h ≤ 438
Part b

Answer:
MN = 68
Step-by-step explanation:
LN = 91
LM = 23
Points L, M, and N are collinear, therefore, according to the segment addition postulate, the following can be deduced:
LM + MN = LN
23 + MN = 91 (Substitution)
Subtract 23 from both sides
23 + MN - 23 = 91 - 23
MN = 68
