One side of the rectangle is exactly 2 cm, the other is 8 cm larger. Build this rectangle and calculate the area and perimeter.

Given:
One side of a rectangle is 2 centimeters long.
The second side b is 8 centimeters larger than the first.

Let’s calculate the length of the second side b of this figure:
b = a + 8 = 2 + 8 = 10 centimeters.
We calculate the area of the quadrangle by the formula S = a * b:
S = a * b = 2 * 10 = 20 cm2.
Find the perimeter of the rectangle by the formula P = a + a + b + b:
P = a + a + b + b = 2 + 2 + 10 + 10 = 24 centimeters.
Answer: the area of the rectangle is 20 cm2 and the perimeter is 24 centimeters.
