Answer:
1
Step-by-step explanation:
"The perimeter P..." gives us one variable to work with.
"is" in this context almost always means "equals".
"the sum" we know we will be adding.
"twice the length l" gives us a variable and a coefficient.
"twice the width w" gives us a variable and a coefficient.
The equation for this is P=2l+2w
I hope in the future you can remember these tips! :)

Answer:
1. Angles 2, 3 and angles 1,3 are complementary angles(Given)
2. To prove :
Since Angles 2, 3 and angles 1,3 are complementary.
When angles are complementary, then the sum of the measures of angles is 90 degrees.
So, and (Definition of Complementary angles)
3. (Substitution)
4. (Subtraction property of equality)
