**Area**

**&**

**Perimeter**

How can we find the PERIMETER?

The perimeter is the distance around an object

Because a rectangle is a shape that has 2 pairs of equal sides, you can do this 2 ways:

ADD

4 + 10 = 14

. MULTIPLY the sum by 2.

14 x 2 = 28.

MULTIPLY

4 x 2 = 8

MULTIPLY

10 x 2= 20

then add products together:

20 + 8 = 28

Can you do this one?

Decide which way works best for you!

First ADD 7 + 4 = 11

Then MULTIPLY the sum by 2.

11 x 2 = 22

OR

MULTIPLY 7 x 2 = 14

MULTIPLY 4 x 2 = 8

Then add the products. 14 + 8= 22

Perimeter (P)= 28mm

Don't forget to put the unit! (mm)

Perimeter (P)= 22 yd

AREA!

Is your answer correct?!

this is the last one

Find the AREA for the section in blue.

Is your answer correct?!

Hint:

It doesn't matter that only 2 sides are given. Remember: a rectangle has 2 pairs of equal sides!

Area is the amount of surfaces that a shape covers. We call these boxes square units.

2 x 4 = 8 sq. units

12 x 7= 84
