| One side of the rectangle is 2 cm longer than the other. The total length of the 2 sides is 12 cm. Find the length of each side of this rectangle
Suppose one side of the rectangle is x cm.
Since the second side of the rectangle is 2 cm larger than the other, its length value will be: x + 2 cm.
The sum of the lengths of the two sides will be:
x + x + 2 = 12.
2 * x = 12 – 2.
2 * x = 10.
x = 10/2 = 5 cm (first side).
x + 2 = 5 + 2 = 7 cm (second side).
The area of the rectangle will be:
7 * 5 = 35 cm2
Answer:
The lengths of the sides are 5 and 7 cm.
