there are 40 dogs and humans in the house. one day someone counted how many legs were in the house and found there were 100 legs in all. how many humans and dogs are there?

10 dogs and 30 humans

Step-by-step explanation: 10 dogs x 4 legs each = 40 legs

30 humans x 2 legs each = 60 legs

40 dog legs + 40 human legs = 100 total legs in the house

10 dogs 30 humans

Step-by-step explanation:

40 ÷ 2 =20

10 × 4 legs =40

30 × 2 legs=60

60 + 40 = 100

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
