Oh, what a lovely collection of sides you have there! To find the perimeter, simply add up all the sides: 2cm + 2cm + 2cm + 3cm + 5cm + 11cm. Just like adding up happy little friends in a painting, you'll get the total perimeter of this shape. Remember, there are no mistakes, just happy little accidents!

The perimeter is the total distance around a two-dimensional shape. To find the perimeter of a shape, you need to add up all the lengths of its sides. In this case, the perimeter of a shape with sides measuring 5cm and 2cm would be 5cm + 5cm + 2cm + 2cm = 14cm.
To find the perimeter of something all you have to do is, MEASURE THE DISTANCE AROUND THE OBJECT, for example if you have a triangle and the left side is 8cm, the right side is 5cm, and the bottom is 3cm, add the three measurements, 8cm + 5cm + 3cm = 16cm
3 + 3 + 5 + 5 = 16cm
To calculate the volume of a rectangular prism, you multiply the length, width, and height together. In this case, the volume would be 2cm x 3cm x 5cm = 30 cubic centimeters. The units for volume are always cubed (cm^3) because you are measuring in three dimensions.
To find the area of a triangle, you use the formula: Area = 1/2 * base * height. In this case, the base is 2cm and the height is 5cm. Plugging these values into the formula, we get: Area = 1/2 * 2cm * 5cm = 5 square centimeters. Therefore, the area of the triangle is 5 square centimeters.
