What is the area 7cm by 4cm
Area = length times width
To find the area of a rectangle, you need to multiply its length by its width. In this case, the length is given as 7cm and the width is given as 4cm. To get the area, you can multiply these two values together:
Area = length × width
Area = 7cm × 4cm
Area = 28cm²
Therefore, the area of a rectangle with dimensions 7cm by 4cm is 28 square centimeters.
