Answer:

154.5+224.4=378.9m

Explanation:

The area of the floor is  3.3 × 10⁵ m²

A floor is rectangular in shape, hence, we use the formula for calculating the area of a rectangle as follows:

Area of a rectangle = Length × Breadth

According to this question, the floor is 1.5 × 10³ m long and 2.2 × 10² m wide. Hence, the length of the floor is 1.5 × 10³ m and the breadth/width is 2.2 × 10² m.

Therefore, the area of the rectangular floor is as follows:

Area = 1.5 × 10³ × 2.2 × 10²

Area = 3.3 × 10^(3+2)

Area of the floor = 3.3 × 10⁵ m²
