Hello there!
Answer:
108 ft²
Explanation:
In this question, we are trying to find the new area of a rectangle in which the sides are increased by 50%.
First thing we must do is find the new size of the side lengths (8 and 6).
We will find a 50% increase in 8, and 50% increase in 6.
We would multiply the numbers by 0.5.
8 × 0.5 = 4
6 × 0.5 = 3
Then, we would add those numbers to the side lengths that it belongs to.
8 + 4 = 12
6 + 3 = 9
The increased side lengths would be 12 (length and 9 (width)
To find the area, you would multiply length × height.
12 × 9 = 108
The area of the new rectangle would be 108 ft²
