The perimeter of the rectangle is 34 cm, the length is 10 cm. Find the area of the rectangle.

A rectangle has equal sides in pairs. The perimeter of a rectangle is calculated as the sum of the lengths of all its sides. Since we know the width of this rectangle, we can find the sum of the lengths of these two sides:
10 * 2 = 20 cm.
Therefore, the sum of the lengths of the other two sides is:
34 – 20 = 14 cm.
The width of the rectangle will be:
14: 2 = 7 cm.
The area of a rectangle is found as the product of its length and width. Let’s calculate the area of this rectangle:
S = 10cm * 7cm = 70cm2.
Answer: S = 70 cm2.
