Think about what you know about perimeter and area. describe hoe to find the perimeter and area of your classroom.

Perimeter : This is defined as the total measurement of all the sides of any closed figure. As given, it is a classroom, so the shape of the classroom should be either square or rectangle.

Perimeter of a rectangle is = 2(length+width)

Perimeter of a square is = 4*side length

Area is defined as the number of unit squares that can be contained in a closed figure.

So, area of a rectangle is given as = length*width

Area of a square is given as = side length*side length.

In general, the classrooms have these shapes only.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
