Find the area and perimeter of the rectangle for which is 5cm and the width is 3cm.

Find the area and perimeter of the rectangle for which is 5cm and the width is 3cm. And find the pyrimeter and the area of the triangle.

A rectangle is a rectangle with equal opposite sides and right angles.

Its area (numerical characteristic of a two-dimensional geometric figure) is calculated by the formula:

S = a * b. Let’s find this value for a rectangle whose width is 3 cm and length = 5 cm:

S = 5 * 3 = 15 cm².

The perimeter is the sum of all sides. It is defined by the formula:

P = 2a + 2b = 2 * 5 + 2 * 3 = 10 + 6 = 16 cm.
