The length of a rectangle is twice it’s with the perimeter of a rectangle is 126 feet.
madreJ [45]

Answer:

Length = 42 feet

Width = 21 feet

Step-by-step explanation:

Let the length and width be represented by L and W

L = 2W

Perimeter (P) = 126 feet

2(L + W) = 126

L + W = 126/2 = 63

2W + W = 63

3W = 63

W = 63/3 = 21 feet

L = 2W = 2 × 21 feet = 42 feet

Need help!!! I don't understand it..
JulsSmile [24]
Okay so every triangle will have 3 angles that add to 180 degrees. You are given that A=65 which means that B + C will have to add to 115. You are given that B= (3x-10) and C=2x, plug this into B+C=115. So
3x-10+2x=115, isolate x, 5x=125, divide both sides by 5 and you get that x=25. This makes B=65, and C=50. Just to check, if you add these together you get 180 degrees.
