Answer 1

Ответ:

Р=2*(4+3)=2*7=14

S=4*3=12

Answer 2

Finding the Perimeter and Area of Rectangle ABCD

To find the perimeter and area of rectangle ABCD, we can use the following formulas:

1. Perimeter of a Rectangle: The perimeter of a rectangle is given by the formula: P = 2*(length + width)

2. Area of a Rectangle: The area of a rectangle is given by the formula: A = length * width

Given: - Length of the rectangle, AB = 4 cm - Width of the rectangle, BC = 3 cm

Calculating the Perimeter

The perimeter of the rectangle ABCD can be calculated using the formula: P = 2*(length + width)

Substituting the given values: P = 2*(4 + 3) = 2*7 = 14 cm

So, the perimeter of the rectangle ABCD is 14 cm.

Calculating the Area

The area of the rectangle ABCD can be calculated using the formula: A = length * width

Substituting the given values: A = 4 * 3 = 12 cm²

So, the area of the rectangle ABCD is 12 cm².

These calculations provide the perimeter and area of the given rectangle.
