The length of one side of the rectangle is 8 cm, a. the length of the other side is three quarters of the length of the first. Calculate the pyrimeter and the area of this rectangle.
1. Determine which is the second side of the rectangle if it is three quarters of the length of the first side, and the first side is 8 cm:
8 * 3: 4 = 6 cm;
2. Determine what area of the rectangle if its sides are 8 cm and 6 cm:
S = 8 * 6 = 48 cm2.
3. Determine what the perimeter of the rectangle is, if its sides are 8 cm and 6 cm:
P = 2 * (8 + 6) = 28 cm.
Answer: the area of the rectangle is 48 cm2, and the perimeter is 28 cm.
