A rectangle with sides 4 cm and 7 cm. Find the perimeter and area of this rectangle.

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 determine this value for a rectangle whose sides are 4 and 7 cm:

S = 4 * 7 = 28 cm².

The perimeter is the sum of all sides. For such a figure, it is determined by the formula:

P = 2a + 2b = 2 * 4 + 2 * 7 = 8 + 14 = 22 cm.
