The length of the rectangle is 2cm less than a decimeter. What is the width of this rectangle if its perimeter is 24cm?

The length of the rectangle is 2cm less than a decimeter. What is the width of this rectangle if its perimeter is 24cm? Find the area of a rectangle.

As you know, 1 dm = 10 cm.That is, the length of the rectangle will be 10 – 2 = 8 cm.
The perimeter of a rectangle is calculated as the sum of the lengths of all its sides. A rectangle has equal sides in pairs. Let’s find the sum of the two sides of a rectangle 8 cm each:
8 cm + 8 cm = 16 cm.
Therefore, we can now calculate the width of the rectangle as follows:
24 cm – 16 cm = 8 cm;
8 cm: 2 = 4 cm.
The area of a rectangle is found as the product of its length and width. Thus, we can calculate the area of a given rectangle:
S = 8cm * 4cm = 32cm2.
Answer: S = 32 cm2.
