Answer:

The width is 13, the length is 17


Step-by-step explanation:

You have to write an expression to represent the area of the rectangle. The width can be w, and the length can be 2w-9. Since the parking lot is a rectangle, you multiply the length by the width to get your area. w(2w-9) is 2w^2-9w=221. The only value of w that satisfies this equation when substituted is 13, so that is your width. 2(13)-9 is 26-9 is 17, so the length is 17.

Can anybody help me with this? <br> This question is confusing and I don't get it.
Lunna [17]

Answer:

JH = 8, GH = 12, and GJ = 10.6

Step-by-step explanation:

According to Midsegment Theorem, a segment that connects the midpoints of two sides of a triangle is half the length of the third side.

GH = ½ DE

JH = ½ DF

GJ = ½ EF

DE is 24, so GH = 12.

JH is half of DF.  Since G is the midpoint of DF, DG is also half of DF.  So JH = DG = 8.

GJ is half of EF.  Since H is the midpoint of EF, HE is also half of EF.  So GJ = HE = 10.6.
