she can wax 33.33 m² of area per hour at the given rate

Step-by-step explanation:

Data provided in the question:

Area of the floor that Jessica waxes = 20 m²

Total Time taken to wax the area = hours

Now,

The rate at which Jessica can wax per hour =

or

⇒ The rate at which Jessica can wax per hour =  m²/hour

or

⇒ The rate at which Jessica can wax per hour =    m²/hour

or

⇒ The rate at which Jessica can wax per hour =  33.33 m²/hour

Hence, she can wax 33.33 m² of area per hour at the given rate
