Let’s find the value of the width of this rectangle, for this we need to divide the value of the length of the rectangle given to us by 4:

20: 4 = 5 cm is the width of this rectangle;

Let’s find the value of the perimeter of the rectangle given to us, for this we need to add the length value with the width of this rectangle, and multiply the result by 2:

(20 + 5) * 2 = 50 cm – the value of the perimeter of the rectangle given to us;

Let’s find the value of the area of ​​the rectangle given to us, for this we need to multiply the value of the width of the rectangle given to us by the value of the length of the rectangle given to us:

20 * 5 = 100 cm2 – the value of the area of ​​the rectangle given to us.

Answer: 50 cm is the value of the perimeter of the rectangle given to us; 100 cm2 – the value of the area of ​​the rectangle given to us.
