Answer:
The perimeter of a rectangle is equal to 2L + 2W, where L = the length of the rectangle and W = the width of the rectangle. So, one equation is
2L + 2W = 60
From the info given in the problem, we also know that L = 4W. Therefore, we can use the Substitution Method to re-write the first equation as:
4W + 2W = 60
You should be able to solve this equation for W. Once you find W, you can then calculate L.

Answer:
BC = 5
Step-by-step explanation:
Of course, this geometry program can tell you the length of BC.
__
If you follow directions, you get a right triangle BCF that has leg lengths 3 and 4. The Pythagorean theorem then tells you the length of hypotenuse BC is ...
BF = 4 -1 = 3
FC = 4 -0 = 4
BC² = BF² +FC²
BC² = 3² +4² = 9 +16 = 25
BC = √25
BC = 5
