Area= length x width. Therefore, Area= 7cm x 4cm=28cm squared.
It is: 4*2 = 8 square cm
Area = 10*4 = 40 square cm
It is 3 cm high.
It could be width = 1 cm, and length = 6 cm: (6 cm) x (1 cm) = 6 cm². It could be 2 cm wide by 3 cm long, which also has area 6 cm². If you are not limited to whole numbers then it could be 1.5 cm wide by 4 cm long, for example, or 0.5 cm wide by 12 cm long.
the volume is 192 sq cm
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 could be width = 1 cm, and length = 6 cm: (6 cm) x (1 cm) = 6 cm². It could be 2 cm wide by 3 cm long, which also has area 6 cm². If you are not limited to whole numbers then it could be 1.5 cm wide by 4 cm long, for example, or 0.5 cm wide by 12 cm long.
It is: 12*6*4 = cubic cm
