The perimeter of the rectangle is 120 cm, the length of the rectangle is 10 cm longer than the width.

The perimeter of the rectangle is 120 cm, the length of the rectangle is 10 cm longer than the width. Find the area of the rectangle.

1. Let the width of the rectangle be c, then the length is c + 10 cm.
2. Let’s compose the equation of the length of the rectangle perimeter and find with:
2 * (c + c + 10) = 120,
4s + 20 = 120,
4s = 120 – 20,
4s = 100,
c = 10/4,
c = 25 cm.
3. Find the length of the rectangle:
25 + 10 = 35 cm.
4. Find the area of the rectangle by multiplying its length by width:
35 * 25 = 875 cm2.
Answer: the area of the rectangle is 875 cm2.
