Based on an idea of Dan Meyer. More or Less: Area & Perimeter. Shape Signature. The signature of a 2-D shape is the ratio of the square of the Semi-Perimeter to the Area. What is the signature of a circle? . of . rectangles. Lesson 3.1: . Perimeter and Area Fluency. What’s the length of the longest side?. What’s the length of. . the opposite side?. What’s the sum of the. . rectangle’s two longest . To find area of rectangle we will count the number of squares, total number of squares will be the area of rectangle which can also be obtained by multiply length and breadth.. Area of rectangle=l x b. 15. Solve word problems . to determine perimeter with given side lengths.. Multiply by . 9 . PATTERN SHEET. 2 minutes. End. Multiply by 7. 7. . x . 9 . = _______. Let’s skip count . by 9.. 9. 18. 27 . given that each unit is equal to 1 cm. 2. .. A = L x W. A = 6 x 9 . A = 54 cm. 2. 6. 9. Find the area for the rectangle. given that each unit is 2 x 2 cm.. A = L x W. A = 12 x 18 . A = 206cm. 2. 2. Formula. Perimeter. Is the distance AROUND . an object. Perimeter . If you started at one point and went all the way around. until you got to where you started, the perimeter is . the total distance you have gone.. WIDTH. WIDTH. We use the . length. and . width. measurements of a rectangle to calculate the perimeter of a rectangle.. We simply add up all the length and width measurements to find the perimeter of something.. Ch 1.7. Formulas. What is perimeter?. The distance around a shape or figure.. What is area?. The amount of space inside of a flat shape. What is circumference?. The perimeter around a circle. How do you know when to use a specific formula?. Perimeter. is the distance around the . . OUTSIDE. of a shape.. To find the perimeter, simply . ADD. the lengths of each . SIDE. . .  . Perimeter is always measured in . LINEAR. . units. . Area. Investigation. Take a piece of paper. Fold it in half twice. . Cut along the layers, cutting out four congruent rectangles. . 3) Find the perimeter and area of one rectangle. . 4) Place two rectangles side by side, creating a rectangle where the length was doubled. . 1.
