Find the area of'a triangle with legs that are: 12 m, 15 m, and 9 m. M
O A. 25.5 m
OB. 38.2 m
OC. 42.4 m
OD. 54 m

The area A of a triangle is given by the formula A=1/2bh where b is the base and h is the height of the triangle. Substitute 14 for b and 10 for h in the formula.

D.  54m

Step-by-step explanation:

by the side you can see that it is a right triangle with hypotenuse = 15

1/2(b)(h) = 1/2(9)(12) = 54

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !
