Calculating Rectangle Area and Dimensions

The video tutorial explains how to calculate the area of a rectangle when its length is increased. Initially, a square with sides of 4T is considered. By adding 4T to the length, the new dimensions become 8 ft by 4T. The area is calculated by multiplying the new length and width, resulting in 32T squared. The tutorial emphasizes the importance of expressing area in square feet.

What are the initial dimensions of the rectangle described in the video?

• 4T by 4T

• 8T by 4T

• 4T by 8T

• 8T by 8T

After adding 4T to the length, what is the new length of the rectangle?

• 4T

• 8 ft

• 16 ft

• 12T

What remains unchanged when 4T is added to the length of the rectangle?

• Perimeter

• Area

• Width

• Length

How do you calculate the area of a rectangle?

• Subtract width from length

• Multiply length by width

• Divide length by width

• Add length and width

What is the area of the new rectangle in square feet?

• 40T squared

• 16T squared

• 32T squared

• 24T squared
