It is: 4*2 = 8 square cm
Area = 10*4 = 40 square cm

The area of a right triangle that has legs 7 cm and 4 cm long can be calculated using the fact that a right triangle is half of a rectangle. The area of a rectangle is l*h, so the area of a right triangle is l*h/2. In this case, the area is 14 cm^2.
The area of rectangle is : 24.0
4*8 = 32 square cm
Area is 16 having output of two dimensions
Area of rectangle: 4 times 10 = 40 square cm
It is: 4*2 = 8 square cm
The area of rectangle is : 20.0
If you meant 4 cm wide then volume is 5*4*6 = 120 cubic cm
Draw a box 3 cm wide by 4 cm long. This box has an area of 12 square centimeters (3 cm X 4 cm = 12 cm2). Or you could do 2 cm wide by 6 cm long. The shape in question has the same area as this box. If you cut out this box in cardboard, and cut out the same shape in question, from the same material, they would both have the same mass.
Area = 10*4 = 40 square cm
It is 3 cm high.
It is: 6*3*4 = 72 cubic cm
It is: 12*6*4 = cubic cm
