noname [10]
You can think of an hour and a half as 75% itself already because you have 3/4 or three thirty minute periods. So every 1/4 is a 30 minute period, and if you multiply 1/4 by 4 you get 4/4 which you ten can convert to 2 hours or 4, 30 minute time periods. (I’m sorry if I explained this in a very confusing manner). It will take Amelia 2 hours in total to finish her drawing.

LuckyWell [14K]

Answer:

Step-by-step explanation:

The formula for determining the area of a rectangle is expressed as

Area = 2(L + W)

Where

L represents the length of the rectangle.

W represents the width of the rectangle.

A proper rectangle has a length of 6 inches and a with of 8 inches. The area of the rectangle would be

6 × 8 = 48 inches^2

A square with a side length of 3 inches was cut of it. The formula for determining the area of a square is l^2

Therefore,

Area of square = 3^2 = 9 inches ^2

The area of the remaining paper would be

48 - 9 = 39 inches^2
