Answer:

I believe the answer is D: 300 inches

Step-by-step explanation:

This might be incorrect, but here's how I see the answer:

First I found the perimeter of one square.

2 + 3 = 5^2= 10

10 inches is the perimeter of one square.

Then, since there is 30 rectangles, and each perimeter is 10 inches long, then you would simply need to multiply the two numbers.

30 * 10 = 300 inches of red thread will be needed.

Answer:

300 in

Step-by-step explanation:

2+2+3+3 = 10

Perimeter 10 for one rectangle.

Multiply 10 by 30 to find out the total perimeter for 30 rectangles.

10 x 30 = 300
