The area of a right triangle with one long leg measuring 5ft and hypotenuse measuring 13ft

30 square feet

Step-by-step explanation:

To find the area of a right triangle you use the formula (leg x leg)/2. So to find the area, first you need to have both of the leg measurements, so you need to use Pythagorean's theorem. After using the theorem, you get 12 feet for the measurement of the other leg, so you multiply 12 by 5. 12 times 5 is 60, so you divide that by 2 (as seen in the original formula) and get your answer of 30.

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
