Performance Task 19
Task 1: Answers may vary about how students estimated
Task 2: One room = 6m x 4m = 24 tiles
Task 3: All the rooms = 15 x 24 tiles = 360 tiles
Task 5: $1968 x 15 = $29, 520.00
Performance Task 21
Task 1: ceiling measures 12m x10m = 120m 2
Task 2 : Length of wall = height = 8m; Width = 10m; Area of wall = 8m x 10m = 80m 2 ;
4 walls = 80m2 x 4 = 320m 2 (minus the 2 windows and doors = 22m2 + 4m2 = 26m2)
New total Area = 294m2
Task 3: Paint 125m2/40l = 3 1/8 tins Approximately 4 tins of paint
Task 4: 300/25 = 14 x 10 = 140 minutes /60 = 2 hours and 20 minutes
Task 5: They will use less than 15 minutes
Rate 1 = 25 square meters to 10minutes = 25/10 = 1 minute to 2.5 square meters
Rate 2 = 25 square meters to 5 minutes = 25/5 = 1 minute to 5 square meters
Total rate for both painters = 1minute to 7.5 square meters.
They would take 50/7.5 = 50 x 2/15 = 6 2/3 minutes. Working at a rate of 1 minute to 7 ½
square meters they would use 6 2/3 minutes to complete 50 square meters.
