En utilisant le théorème de Pythagore : \( 8^2 + b^2 = 10^2 \).


Solve for \( w \):
\( w = 8 \) meters.
The area is \( \text{length} \times \text{width} = 24 \times 8 = 192 \) square meters.
A car travels 150 miles using 5 gallons of gas. If gas costs $3.50 per gallon, what is the total cost to travel 450 miles?
First, find the car's fuel efficiency:
\( \frac{150 \text{ miles}}{5 \text{ gallons}} = 30 \text{ miles per gallon} \).
Next, find how many gallons are needed for 450 miles:
\( \frac{450 \text{ miles}}{30 \text{ miles per gallon}} = 15 \text{ gallons} \).
Then, calculate the total cost:
\( 15 \text{ gallons} \times \$3.50 \text{ per gallon} = \$52.50 \).
