The floor of the school art closet is being tiled. The closet is shaped like a parallelogram. The parallelogram has a base of 17.5 feet and a height of 6 feet. Each package of tile will cover 5 square feet. How many packages of tile will be needed to tile the art closet floor?

21  packages

Step-by-step explanation:

We need to identify the area of the parallelogram. Given that:

=> S = bh = 17.5 x 6 = 105 ft²

Area covered by 1 package of tile = 5 ft²

So the number of packages of tile will be needed to tile the art closet floor:

The area of the parallelogram / Area covered by 1 package of tile

= 21  packages

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
