A rectangle has a length of 10 ft and a width of 6 ft. What's the perimeter?
A) 16 ft
B) 60 ft
C) 26 ft
D) 32 ft
Answer (2)
The problem provides the length and width of a rectangle.
The perimeter formula P = 2 l + 2 w is used.
Substitute the given length l = 10 ft and width w = 6 ft into the formula.
Calculate the perimeter: 32 ft .
Explanation
Problem Analysis We are given a rectangle with length l = 10 ft and width w = 6 ft. We need to find the perimeter of the rectangle.
Perimeter Formula The formula for the perimeter of a rectangle is given by: P = 2 l + 2 w where P is the perimeter, l is the length, and w is the width.
Substitution Substitute the given values of length and width into the formula: P = 2 ( 10 ft ) + 2 ( 6 ft )
Calculation Perform the calculations: P = 20 ft + 12 ft P = 32 ft
Final Answer The perimeter of the rectangle is 32 ft. Therefore, the correct answer is OD) 32 ft.
Examples
Understanding the perimeter of a rectangle is useful in many real-life situations. For example, if you're building a rectangular fence around a garden, you need to know the perimeter to determine how much fencing material to buy. Similarly, if you're decorating a rectangular room with a border, knowing the perimeter helps you calculate the length of the border needed. These practical applications make understanding perimeter essential for everyday tasks.
The perimeter of the rectangle is calculated using the formula P = 2 l + 2 w . By substituting the given length of 10 ft and width of 6 ft, we find that the perimeter is 32 ft. The correct answer is D) 32 ft.
