Answer 1

The painting could be 5ft high and 12ft long, or it could be 4ft high and 15ft long, or it could also be 6ft high and 10 ft long

Answer 2

Answer:  

Length = 5 feet and Height = 12 feet

Step-by-step explanation:

An art class is planning to paint a rectangular mural with an area of 60 square feet.

⇒  Area = 60 square feet

The measure of length > 4 feet

Also, The measure of height > 6 feet

Now, to find the required length and height in whole numbers in order to paint the complete area of 60 square units

⇒ Length = 5 feet

⇒ Height = 12 feet

Thus, Area = 12 × 5 = 60 = Area of the room which is to be painted.

Hence, Length = 5 feet and Height = 12 feet
