Question

a gardener is planning to plant a border of flowers around a rectangular garden that measures 15 meters (lets assume in length, and 10 meters in width). which of the following is the total length of flower border needed for the garden? 150 m 25 m 100 m 50 m

Explanation:

Step1: Recall the perimeter formula for a rectangle

The perimeter \( P \) of a rectangle is given by \( P = 2\times (l + w) \), where \( l \) is the length and \( w \) is the width.

Step2: Identify the length and width

From the problem, the length \( l = 15 \) meters and the width \( w = 10 \) meters.

Step3: Substitute the values into the formula

Substitute \( l = 15 \) and \( w = 10 \) into the perimeter formula: \( P = 2\times(15 + 10) \).
First, calculate the sum inside the parentheses: \( 15 + 10 = 25 \).
Then, multiply by 2: \( 2\times25 = 50 \).

Answer:

50 m (the option with 50 m)
