The length of a rectangular classroom is 60 feet. the perimeter if the classroom is 220 feet. what is the area of the classroom

Length = 60 feet
Perimeter = 220 feet

There's four sides to a rectangle if one side is 60 then that means there are two sides that 60 because they are opposite each other.

So side A=60 and side B = 60

Now you have two sides left. Add the two sides you have to get 120

Subtract 120 from 220 = 100

Now divide 100 by 2 to get the remainder side lengths which is 50

So side C=50 and side D=50

Area is base times height so in this case it would be 50 times 60 since those are adjacent sides

And your answer is 3000 feet

Hope this helped!
