Sure, to find the area of a rectangle, we simply multiply its length by its width. Here, the length of the trampoline's jumping surface is given as 10.3 feet, and the width is given as 9.2 feet.
Step 1: Write down the length and width.
Length = 10.3 feet
Width = 9.2 feet
Step 2: Multiply the length by the width.
Area = Length × Width = 10.3 feet × 9.2 feet
Perform this multiplication to get the area.
Result: The area of the jumping surface of the trampoline is 94.76 square feet.
This means that the total surface area upon which someone can jump on the trampoline is 94.76 square feet.
