Answer 1

Answer:

• 94.5 in²

Step-by-step explanation:

Given

• Area of glass display box is 378 in²
• The scale factor is 1/2

We know that the area is the function of two dimensions

To find the surface area of the display box we need to multiply the surface area of the original by the square of the scale factor

• A = (1/2)²*378 = 378/4 = 94.5 in²
