Calculation of Perimeter and Area of a Rectangle

To find the perimeter and area of a rectangle, we need to know the length and width of the rectangle. In this case, the length of the rectangle is given as 42 cm, and the width is 6/7 of the length.

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

Step 1: Calculate the Width The width of the rectangle is given as 6/7 of the length. To find the width, we can multiply the length by 6/7.

Width = Length * (6/7) = 42 cm * (6/7) = 36 cm.

Step 2: Calculate the Perimeter The perimeter of a rectangle is the sum of all its sides. In this case, the rectangle has two sides of length 42 cm and two sides of length 36 cm.

Perimeter = 2 * (Length + Width) = 2 * (42 cm + 36 cm) = 2 * 78 cm = 156 cm.

Therefore, the perimeter of the rectangle is 156 cm.

Step 3: Calculate the Area The area of a rectangle is given by the formula: Area = Length * Width.

Area = Length * Width = 42 cm * 36 cm = 1512 cm^2.

Therefore, the area of the rectangle is 1512 cm^2.

To summarize: - Perimeter of the rectangle: 156 cm. - Area of the rectangle: 1512 cm^2.
