PLEASE HELP Grace is making a display board for the school talent show. The display board is a 6 ft by 11 ft rectangle. She needs to add a ribbon border around the entire display board. What is the length of ribbon that she needs?

127 millimeters is the answer

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
