279 in² is the answer

To find the approximate area of a right triangle, you can use the formula:

Area = (1/2) * base * height

In your case, "a" is the base and "c" is the hypotenuse. To find the height, you can use the Pythagorean theorem since it's a right triangle:

c^2 = a^2 + height^2

34^2 = 27^2 + height^2

1156 = 729 + height^2

Now, subtract 729 from both sides:

height^2 = 1156 - 729

height^2 = 427

Take the square root of both sides:

height ≈ √427

height ≈ 20.71 inches (rounded to two decimal places)

Now, you can find the area:

Area = (1/2) * a * height

Area = (1/2) * 27 in * 20.71 in

Area ≈ 277.695 square inches

Rounding to the nearest whole number, the approximate area of the triangle is 278 square inches. None of the provided answer choices exactly match this value, but the closest one is 279 in². So, 279 in² is the closest approximate area among the options given.
