Step-by-step explanation:
The rectangle has an area of 
The width of the rectangle is equal to the greatest common monomial factor of
and
Find this monomial factor:

Hence, the width of the rectangle is
units.
The area of the rectangle can be rewritten as

The area of the rectangle is the product of its width by its length, then the length of the rectangle is
units.
Answer: 30 trees
Step-by-step explanation:
Elizabeth has 330 citrus trees and 180 palm trees
The largest number of trees that she can have in a row will base on the highest common factor between the two number of trees
330 = 2 × 3 × 5 × 11
180 = 2 × 2 × 3 × 3 × 5
HCF = 2 × 3 × 5
HCF = 30
The largest number of trees that she can have in a row is 30 trees.
