Question

Cheryl wants to put Legos all around the outside of her square Lego mat to make a border. The mat has a perimeter of 48 inches. Each Lego piece is one-inch long. She has enough Legos to complete 2 sides of her mat. How many Legos are needed to complete this border? a) 48 Legos b) 24 Legos c) 96 Legos d) 72 Legos

Answer 1

Cheryl needs 24 Legos to complete the border.

Step-by-step explanation:

To find the number of Legos needed to complete the border, we need to calculate the perimeter of the square Lego mat. The problem states that the perimeter is 48 inches. Since each Lego piece is 1 inch long, there are 48 Legos needed for the entire perimeter. However, Cheryl only has enough to complete 2 sides of the mat, so we divide the total number of Legos needed by 2.

48 Legos ÷ 2 = 24 Legos

Therefore, the answer is 24 Legos (option b).
