18/12 = 3 : 2 or 1.5 : 1 or one and a half to one.
The area of rectangle is : 72.0
You can't calculate the volume here as such the height is not mentioned here and for calculating volume you need height,breadth and length.
36 cm2 Area of a rectangle is length times width, so you would multipy 12cm by 3 cm to get 36 sq. (squared) cm.
12cm
15 cm Solved through Pythagoras' theorem.
Area = length * height. A = 20cm * 12cm A = 240 cm2
Area of the rectangle is 144cm. The sides of a square with the same ares is 12cm.
The perimeter of a rectangle is simply the sum of its four sides. In this case - 12 + 19 + 12 + 19 = 62
area = length x width area = 12 x 10 = 120 square cm
The area of rectangle is : 168.0
The area of rectangle is : 48.0
