The length of the rectangle is 10 cm and the width is 7 cm. What is its area?

The length of the rectangle is 10 cm and the width is 7 cm. What is its area? The length of the diameter of the circle is 60 cm. What is the length of the radius?

First task:

Area (S) is calculated using the formula:

S = A * B, where A is one side, B is the second.

Consequently:
Area of the rectangle: 10 * 7 = 70 (see square).

Second task:
The radius of a circle, a point that is at an equal distance from the center, it is equal to half the diameter, hence the length of the radius:

60: 2 = 30 cm.
