Question

В прямоугольнике а 16 см сторона б на 8 см больше найдите периметр и площадь прямоугольника

Answer 1

Ответ:

Р=80см,площадь=384 см.

Пошаговое объяснение:

а то есть 16 + б то  есть 8= 24 см-б

Р-16*2+24*2=80см

площадь- 16*24=384см квадратных

Answer 2

Perimeter and Area of a Rectangle

To find the perimeter and area of a rectangle, we need to know the lengths of its sides. In this case, we are given that side A is 16 cm and side B is 8 cm longer than side A.

Let's calculate the perimeter and area of the rectangle:

1. Perimeter: The perimeter of a rectangle is the sum of all its sides. In this case, we have two sides: A and B.

The length of side A is given as 16 cm. The length of side B is 8 cm longer than side A, so it is 16 cm + 8 cm = 24 cm.

To find the perimeter, we add the lengths of both sides: Perimeter = Side A + Side B = 16 cm + 24 cm = 40 cm.

Therefore, the perimeter of the rectangle is 40 cm.

2. Area: The area of a rectangle is calculated by multiplying the lengths of its sides. In this case, we have side A and side B.

The length of side A is given as 16 cm. The length of side B is 8 cm longer than side A, so it is 16 cm + 8 cm = 24 cm.

To find the area, we multiply the lengths of both sides: Area = Side A * Side B = 16 cm * 24 cm = 384 cm².

Therefore, the area of the rectangle is 384 cm².

So, the perimeter of the rectangle is 40 cm and the area is 384 cm².
