Answer:
1044 cm²
Step-by-step explanation:
Split the shape up into two
Area of shape A:
Area = length × width
To calculate the width = 46 - 21 = 25 cm
Area = 30 cm × 25 cm = 750cm²
Area of shape B
Area = length × width
Area = 14 cm × 21 cm = 294 cm²
Add up both of the areas:
750 cm² + 294 cm² = 1044 cm²
Answer: it would take them 40/13 hours
Step-by-step explanation:
If Naomi were to paint her living room alone, it would take 5 hours. it means that the rate at which she paint her living room alone is 1/5
Her sister Jackie could do the job in 8 hours. it means that the rate at which Jackie paint the living room is 1/8
If they work together, they would work simultaneously and their individual rates are additive. This means that their combined working rate would be
1/5 + 1/8 = (8 + 5)/40 = 13/40
Assuming it takes t hours for both of them to clean the room working together, the working rate per hour would be 1/t. Therefore,
13/40 = 1/t
t = 40/13 hours
