If AC equals 48 meters, what is the perimeter of the field
Alinara [238K]

Remark

A kite is constructed such that AB = BC and AD = DC. AB = sqrt( (1/2)AC + 18^2) see diagram. AD = sqrt(24^2 + 32^2)

Step One

Solve for AB

1/2 AC = 24 (AC is given as 48)

18 is a given length

AB = sqrt(24^2 + 18^2) = sqrt(576 + 324) = sqrt(900) = 30

Step Two

Find the length of AD

AD = sqrt(32^2 + 24^2) = sqrt(1024 + 576) = sqrt(1600) = 40

Step Three

Find the Perimeter.

P = 2 * 30 + 2*40 = 60 + 80 = 140

P = 140 <<<<< Answer

Find the least common multiple of 10 and 14.
aksik [14]
We can do this by just adding 14 to 14 until we get a number that is divisible by 10.  We can do it this way because it will be a small number.  Let's list them out.  14, 28, 42, 56, 70.  70 is divisible by 10, so 70 is the answer.
