Math Problem Statement

A rectangle is 19 feet long and 3 feet wide. Find its area.

Solution

To find the area of a rectangle, we use the formula:

Area=Length×Width\text{Area} = \text{Length} \times \text{Width}

In this case, the length is 19 feet and the width is 3 feet. Thus,

Area=19ft×3ft=57square feet\text{Area} = 19 \, \text{ft} \times 3 \, \text{ft} = 57 \, \text{square feet}

The correct answer is A: 57 square feet.

Here are 5 related questions to explore:

  1. What is the perimeter of the rectangle?
  2. How would the area change if the length were doubled?
  3. How do you find the area of other shapes like triangles and circles?
  4. If the dimensions of the rectangle were in meters instead of feet, how would you convert the area to square meters?
  5. How does the formula for the area of a rectangle relate to the area of a parallelogram?

Tip: Remember, the area of any rectangle is always the product of its length and width, so if you know these two dimensions, you can always calculate the area easily.
