Final answer:
Hana will need 246 meters of fencing to build 3 cricket courts in the local park.
Step-by-step explanation:
Hana plans to build 3 cricket courts in a local park. Each court is the same size and measures 30 m by 11 m. To calculate the amount of fencing needed, we need to find the perimeter of one court and then multiply it by 3.
Step 1: Find the perimeter of one court by adding the measurements of all four sides: 30 + 11 + 30 + 11 = 82 meters.
Step 2: Multiply the perimeter of one court by 3 to find the total amount of fencing needed: 82 x 3 = 246 meters.
