Question: A rectangular field is 50 meters long and 30 meters wide. If a fence is built around it, what is the total length of the fence?

Options:

Correct Answer: 160 m

Solution:

Perimeter = 2(length + width) = 2(50 + 30) = 2 × 80 = 160 m.

A rectangular field is 50 meters long and 30 meters wide. If a fence is built around it, what is the total length of the fence?

Step 1: Identify the length of the rectangular field, which is 50 meters.
Step 2: Identify the width of the rectangular field, which is 30 meters.
Step 3: Use the formula for the perimeter of a rectangle, which is Perimeter = 2(length + width).
Step 4: Substitute the length and width into the formula: Perimeter = 2(50 + 30).
Step 5: Calculate the sum inside the parentheses: 50 + 30 = 80.
Step 6: Multiply the result by 2: 2 × 80 = 160.
Step 7: The total length of the fence is 160 meters.
