1. 6.11 determine if a problem situation involving polygons of four or fewer sides represents the application of perimeter or area and apply the appropriate formula     

2. Pg 59 • Directions- • MA and PA….multiply area and perimeter add. • Draw a picture of the situation to determine if it is area or perimeter. Label the measurements. • Apply formulas and solve • Key words- • Area- cover, carpet, grass, mow, an area, paint, tile • Perimeter- fence, trim, border, enclose, hem, edge, around • Practice- • 1. Table cloth covers 6ft x 4 ft table. • 2. Sew a trim on a table cloth that is 6 ft x 4 ft. • 3. Paint a wall that is 10 ft x 8 ft. • 4. How much frosting for a triangular shaped cake that’s base 5 inches and height is 2 inches • 5. Sewing a ribbon around a triangle with a base of 8 inches and two sides each 7 inches. 6.11 Vocabulary Polygon –A polygon is a simple, closed, two-dimensional figure formed by three or more sides. Area– It is the product of the length and the width (A = lw). The area of a triangle is one half of the measure of the base times the height: A = bh, or A = bh ÷ 2. Perimeter– The perimeter of a polygon is the measure of the distance around the polygon. Length(l) - The measurement of the extent of something along its greatest dimension. Width(w) - The measurement of the extent of something from side to side. Base(b) – Bases are the top and bottom faces of a three-dimensional object. Height(h) –The shortest distance from the base of a parallelogram to its opposite side. FORMULAS Area = L X W Area= bh / 2 (half a quad) Perimeter is adding up all the sides MA PA
