What is the formula for calculating the area of a rectangle?

Back

A = L x W, where A is the area, L is the length, and W is the width.

Front

If a swimming pool has an area of 120 square meters and a width of 4 meters, how do you find the length?

Back

Use the formula A = L x W. Rearranging gives L = A / W. So, L = 120 / 4 = 30 meters.

What is the area of a rectangle with a width of 5 cm and a length of 50 cm?

Back

Area = L x W = 50 cm x 5 cm = 250 square centimeters.

Front

What does the term 'partial product' refer to in multiplication?

Back

A partial product is the result of multiplying a single digit of one factor by the entire other factor.

Front

In the area model for multiplication, how is the area represented?

Back

The area is represented as the product of the lengths of the sides of the rectangle formed by the factors.

Front

What is the missing width in the area model for 7 x 63 if one side is 7?

Back

The missing width is 3, since 7 x 3 = 21 and 7 x 63 = 441.

Front

How do you calculate the area of a rectangle if you know the length and width?

Back

Multiply the length by the width (A = L x W).

Front

What is the significance of understanding area in real-world applications?

Back

Understanding area helps in determining the size of spaces, such as rooms, land, and pools, which is essential for planning and design.

Front

What is the relationship between area and multiplication?

Back

Area is a product of two dimensions (length and width), which involves multiplication.

Front

How can you verify the area of a rectangle?

Back

You can verify the area by measuring the length and width, then calculating A = L x W and comparing it to the expected area.
