142. Practice Time!

143. 1) Find the perimeter of this rectangle. 25 cm 12 cm 25 cm

144. 1) Find the perimeter of this rectangle. 25 cm 12 cm 25 cm 25 cm + 12 cm + 25 cm + 12 cm = 74 cm

145. 2) Which expression shows how to find the perimeter of the rectangle and uses distributive property? 3 cm 2 cm 3 cm 2 x 3 2 + 3 2 + 3 + 2 + 3 2 x (2 + 3)

146. CORRECT! 3 cm 2 cm 3 cm 2 x (2 + 3) If you add 2 and 3, you get half of the perimeter. If you double this sum, then you get the entire perimeter.

147. Incorrect! This does NOT show the distributive property. 3 cm 2 cm 3 cm 2 + 3 + 2 + 3

148. Incorrect! This would only result in half of the perimeter. 3 cm 2 cm 3 cm 2 + 3

149. Incorrect! This would result in the area of the rectangle 3 cm 2 cm 3 cm 2 x 3

150. 3) Choose the two expressions that would give the perimeter of this regular pentagon. 8 cm A) 8 + 8 + 8 + 8 + 8 B) 5 + 5 + 5 + 5 + 5 C) 8 x 5 D) 8 + 5

151. 3) Choose the two expressions that would give the perimeter of this regular pentagon. 8 cm A) 8 + 8 + 8 + 8 + 8 B) 5 + 5 + 5 + 5 + 5 C) 8 x 5 D) 8 + 5

152. 4) Find the perimeter of this rectangle. 1.3 cm.85 cm 1.3 cm

153. 4) Find the perimeter of this rectangle. 1.3 cm.85 cm 1.3 cm.85 cm 1.30 cm.85 cm 1.30 cm + Line up place columns.
