Imagine a rectangle with sides of $$14$$ and $$21 \ cm$$. Calculate the perimeter and area.

See development and solution

### Development:

The perimeter is the sum of the sides: $$$P=2(14 +21)=70 \ cm$$$

The area of the rectangle is: $$$A=14\cdot21=294 \ cm^2$$$

### Solution:

$$P=70 \ cm$$

$$A=294 \ cm^2$$
