For 1.
Solution,
Sides(l)= 3.5
Now,
Perimeter of square=4l
=4*3.5
=14
Then,
Area of square =l^2
=3.5*3.5
=12.25
For 2.
Solution,
Sides(l)=1
Now, perimeter of square =4l
=4*1
=4
Then,
Area of square =l^2
=1*1
=1
For 3.
Solution,
Sides(l)= 20
Now,
Perimeter of square=4l
=4*20
=80
Then,
Area of square =l^2
=20*20
=400
We will use the Pythagorean theorem to determine the height:
Finally:
Answer Ladder will reach the height of 14.59 feet ( to the nearest hundredths).
-18f - 34 - 14f = 11
-32f - 34 = 11
-32f = 45
f = -32/45
Simplify the fraction if needed!

Answer:
(22/12 - 33/12) - 8/12 + 10/12 + 6/12
(-11/12)+ 8/12
-3/12= -1/4
