Step-by-step explanation:
To find a set of 3 leg lengths that will form a right-angled triangle, the square of the largest leg must be equal to the sum of the squares of the other 2 legs.
We try out all the options:
39² = 1521, 15² + 36² = 1521.
12² = 144, 8² + 4² = 80.
17² = 289, 13² + 9² = 250.
Since 39² equals 15² + 36², option A is the correct answer.
398,422 = 390,000

Just simply use the calculation of a trapazium.
[ (6+7) + 21 ][6]
---------------------
2
that's the formula of a trapazium. add the top length and bottom length, multiply it by the height and divide all of them by 2.
now the answer should be A, 102.
