Guidance on solving exercise 3 on page 50 of Math 5 textbook practice

Problem:
A rectangle has a width of 16.34m, and its length is 8.32m more than its width. Calculate the perimeter of that rectangle.

Solution Method:
- The problem details:
+ Width: 16.34 m
+ Length is 8.32 m more than the width
- The problem requirement: Calculate the perimeter of the rectangle.
- How to solve:
+ Find the length of the rectangle by adding the width measurement to the measurement by which the length exceeds the width.
+ Calculate the perimeter of the rectangle by adding the given width to the found length, multiplied by 2.

Answer:
The length of the rectangle is:
16.34 + 8.32 = 24.66 (m)
The perimeter of the rectangle is:
(24.66 + 16.34) x 2 = 82 (m)
Answer: 82 m.

Frequently Asked Questions

What is the method to calculate the perimeter of a rectangle?

To calculate the perimeter of a rectangle, first, find the length by adding the width to the additional length. Then, use the formula: Perimeter = 2 × (Length + Width). In this case, the perimeter is calculated by taking the found length and the given width, multiplying the sum by 2.

How do you determine the length of the rectangle from its width?

To determine the length of the rectangle, add the width to the extra measurement provided. For example, if the width is 16.34 m and the length exceeds the width by 8.32 m, the length would be 16.34 m + 8.32 m, resulting in 24.66 m.

Is the answer to the perimeter of the rectangle on page 50 correct?

Yes, the calculated perimeter of the rectangle is correct. It totals 82 meters, achieved by adding the length and width together and multiplying by 2, confirming accurate application of the perimeter formula.
