Answer
120 inches by 240 inches.
Work Step by Step
Each square is 12 inches so you have to multiply each measurement by 12.
The width is 20 squares. So, 20*12=240 inches width
The length is 10 squares. So, 10*12=120 inches length.
12 inches equal 1 foot. So you could change it to 20 feet wide,10 feet long or you can write it as 240 inches by 120 inches.
