What is the formula for the area of a rectangle?

Back

The area of a rectangle is calculated using the formula: Area = length × width.

How do you proportionally resize an object?

Back

To proportionally resize an object, maintain the same ratio of dimensions. For example, if a logo is 7 inches high and needs to be 8 feet high, calculate the new dimensions by scaling up using the ratio of the new height to the original height.
