Answer: The area is 1 1/4. The perimeter is 6.

Step-by-step explanation: 2.45 is about 2.5. 5/8 is about 1/2. To find the area we need to multiply length times width. 2.5 is 2 and 1/2 which is 5/2. 5/2 times 1/2 is 5/4. To simplify it divide 5 by 4 which is 1 with remainder 1. 5/4 is 1 1/4. Therefore the area is 1 1/4 meters squared. To find the perimeter we have to add length + length + width + width. . 2.5 is the same thing as 2 1/2. 5/8 is about 1/2 if we use benchmarks. 2 1/2 + 2 1/2 + + 1/2 + 1/2 is 6. The perimeter is 6.
