Answer 2

Perimeter of a Rectangle

To find the perimeter of a rectangle, you need to add up the lengths of all its sides. In this case, the perimeter of the rectangle is given as 210 cm, and its width is 26 cm. Let's calculate the length of the rectangle.

Let's assume the length of the rectangle is L.

The formula for the perimeter of a rectangle is: Perimeter = 2 * (Length + Width)

Substituting the given values: 210 cm = 2 * (L + 26 cm)

To find the length of the rectangle, we can solve this equation.

Solving for the Length

Let's solve the equation to find the length of the rectangle.

210 cm = 2 * (L + 26 cm)

Divide both sides of the equation by 2: 105 cm = L + 26 cm

Subtract 26 cm from both sides of the equation: 105 cm - 26 cm = L 79 cm = L

Therefore, the length of the rectangle is 79 cm.

Area of a Rectangle

To find the area of a rectangle, you multiply its length by its width. In this case, the length is 79 cm and the width is 26 cm.

The formula for the area of a rectangle is: Area = Length * Width

Substituting the given values: Area = 79 cm * 26 cm

Calculating the area: Area = 2054 cm²

Therefore, the area of the rectangle is 2054 cm².
