The rectangle is 6 cm wide and 75% longer than the width. Find the area of the rectangle.

To solve this problem, recall the formula for the area of a rectangle. The area of the rectangle is equal to the product of the length and the width. S = a * b, where a is the length and b is the width. Knowing that the width is 6 cm and the length is 75% longer, we calculate the length of the rectangle. Remember, to find the percentage of the number, you need to multiply the number by the percentage and divide by one hundred. Let’s calculate 75% of 6.
75 * 6/100 = 4.5.
The length is equal to:
4.5 + 6 = 10.5 cm.
Let’s calculate the area of the rectangle.
S = 10.5 * 6 = 63 cm ^ 2.
Answer: 63 square centimeters.
