54.75 square feet is the answer
Answer: 
Explanation:
Since we have given that
line m and line n are parallel to each other,
So,
Corresponding angles are equal , as shown in the figure ,
According to question,
Hence,
Answer:
12
Step-by-step explanation:
2(a+3)
Given a = 3, all you need to do is just plug in a = 3 into the expression
2(3 + 3)
= 2 (6)
= 12
For example, to find two ratios that are equal to 1:7, first write 1:7 as the fraction 1/7. ... Next, multiply both the numerator and denominator of 1/7 by 2, to get 2/14, or 2:14, and multiply the numerator and denominator of 1/7 by 3, to get 3/21, or 3:21.
