First of all, let’s calculate what the length of the rectangle is.
12 + 8 = 20 centimeters.
Let’s calculate what is the area of a rectangle 20 cm long and 12 cm wide.
S = 20 * 12 = 240 cm².
Let’s calculate what the perimeter is. To do this, find the doubled sum of the length and width.
P = 2 * (12 + 20) = 2 * 32 = 64 cm.
Answer: 64 cm, 240 cm².
