The length of a rectangle is twice its width. The perimeter is 60 ft. Find its area.
1 answer:
Answer:
200 feet squared
Step-by-step explanation:
W=Width
2W=Length
Perimeter = 2*Length + 2*Width
Now use substitution for the Length
60 = 2(2W) + 2(W)
60=4W + 2W = 6W divide both sides by 6
60/6 = 6W/6
10 = W
Width = 10 and Length is twice as long so it is 20. 10+10+20+20=60
The area is Length * Width = 20*10=200
