## Answer :

The relationship between linear scale factor and **area scale factor** can be

used to find the area of the window after it is enlarged.

- The area of the window after it is enlarged is
__72 square feet__

**Reasons**:

The length of the window =** 4 feet**

The width of the window = **8 feet**

The scale factor the manufacturer wants to use, LSF =** 1.5**

**Required**:

The area of the **window **after it is enlarged

**Solution**:

The scale factor of area, Area SF = The **square **of the **length **scale factor, **LSF**²

Therefore;

**Area SF** = 1.5² = 2.25

Area of the window after it is enlarged = **Original area × 2.25**

The original area = 8 ft. × 4 ft. = **32 ft.²**

Therefore;

Area of the window after it is enlarged = 32 ft.² × 2.25 = __72 ft.²__
