A rectangle 8 centimeters by 15 centimeters has a perimeter of 46 centimeters (2l + 2h) and an area of 120 centimeters (l * h).
15 cm^2
It is: 30*15*12 = 5400 cubic cm
15 cm for the diagonal.
The ratio is 3:2
To find the area of a rectangle, you multiply its length by its width. In this case, the rectangle is 3 cm long and 9 cm wide. So, the area would be 3 cm x 9 cm = 27 square cm.
15 cm long and 5 cm wide is pretty nearly 15 cm long.
10 cm wide and 15 cm long
15 cm^2

It is: 30*15*12 = 5400 cubic cm
Area = 15*12 = 180 square cm

The area of a rectangle is calculated by multiplying its length by its width. For a rectangular photo that is 20 cm long and 15 cm wide, the area would be 20 cm × 15 cm = 300 cm². Thus, the area of the photo is 300 square centimeters.
To find the perimeter of a rectangle, you can use the formula: Perimeter = 2(length + width). For a rectangle that is 14 cm long and 4 cm wide, the perimeter would be: 2(14 cm + 4 cm) = 2(18 cm) = 36 cm. Therefore, the perimeter is 36 cm.
Multiply 20 x 15 x 78 = 23400 cubic cm = 1428 cubic inches
It is an area measurement. Think of taking 15 1x1 cm square tiles and putting them all in a row. The area of that row if 15 cm long and 1 cm wide so it is 15 cm squared.
A queen-size mattress is 60" wide by 80" long (152 cm wide by 203 cm long). A king-size mattress is 76" wide by 80" long (193 cm wide by 203 cm long). A California king-size mattress is 72" wide by 84" long (182 cm wide by 213 cm long).
