Given:
The wall is 13 ft. by 19 ft.
A sheet of drywall measures 6ft. by 5 ft.
Required:
We need to find the number of the drywall sheet needed to cover the wall.
Explanation:
Multiply 13 and 19 to find the area of the wall.
[tex]The\text{ area of the wall = 13}\times19=247\text{ ft}^2[/tex]
Multiply 6 and 5 to find the area of the drywall.
[tex]\text{The area of the drywall =6}\times5=30ft^2[/tex]
Divide the area of the wall by the area of the drywall to find the number of the drywall sheet needed to cover the wall.
[tex]T\text{he number of the drywall sheet needed to cover the wall =}\frac{247}{30}=8.23[/tex]
Teddy needs 8 sheets of drywall to cover the wall.
Final answer:
Teddy needs 8 sheets of drywall to cover the wall.
