Find the Perimeter AND the Area of the shape below

A = b h A = 5 x 3 A = 15 ft2 3 ft 5 ft

Perimeter means to ADD up all the sides 5 ft 3 ft 3 ft 5 ft 5 + 5 + 3 + 3 = 16 ft

Ch. 6-1 A Order of Operations

Please Excuse My Dear Aunt Sally P.E.M.D.A.S Please Excuse My Dear Aunt Sally Parenthesis ( ) Exponents 23 Multiply OR Divide Add OR Subtract The last 2 parts you DON’T do in order, you do whichever you see FIRST!!!

Expressions – combine numbers and operations Multiply comes first! 4 + 3 x 5 4 + 15 = 19

Make sure to follow the proper order! 10 – 2 + 8 For + and – you do the FIRST one you see!!! 10 – 2 + 8 8 + 8 = 16

Rewrite after EVERY step! 20 ÷ 4 + 17 x (9 – 6) 20 ÷ 4 + 17 x (9 – 6) Parenthesis 20 ÷ 4 + 17 x 3 20 ÷ 4 + 17 x 3 Divide 5 + 17 x 3 5 + 17 x 3 Multiply 5 + 51 = 56

Exponents can be tricky! Exponents mean 6 x 6 NOT 6 x 2! 3 x 62 + 4 3 x 36 + 4 3 x 36 + 4 Multiply 108 + 4 = 112

Lets try this…ALL the steps! 96 ÷ 42 + (25 x 2) – 15 - 3 96 ÷ 42 + 50 – 15 - 3 96 ÷ 16 + 50 – 15 - 3 6 + 50 – 15 - 3 56 – 15 - 3 41 – 3 = 38

Use this for certain word problems Alexis and 3 friends decide to have a snack at the mall. Each person buys a hot pretzel for $3, a dipping sauce for $1, and a drink for $2. Write an expression for the total cost and then find the total cost. $3 x 4 + $1 x 4 + $2 x 4 12 + $1 x 4 + $2 x 4 12 + 4 + $2 x 4 12 + 4 + 8 = 24
