ABC Elementary wants to purchase new computers for their school. They are curious how the new laptops compare to their current ones in terms of space as their enrollment numbers are increasing and space is not. What would the surface area be if the length is 13 inches, the width is 7.5 inches? The triangle's hypotenuse is 10.61 inches. Round the answer to the nearest hundredth if necessary.

Answer 1

To find the surface area of a triangle, we use the formula:

\[ \text{Surface area} = \frac{1}{2} \times \text{length} \times \text{width} \]

Given:
Length = 13 inches
Width = 7.5 inches

Plugging in the values:

\[ \text{Surface area} = \frac{1}{2} \times 13 \times 7.5 \]
\[ \text{Surface area} = \frac{1}{2} \times 97.5 \]
\[ \text{Surface area} = 48.75 \text{ square inches} \]

Therefore, the surface area of the triangle is 48.75 square inches.
