Answer 1

so you need calculi area of 2 right triangles so what are congruent so what mean that you calculi area of one from these and just multiplie it by 2
- so and there are two rectangular sides ,with length 12 and 15 and width 10 so than calculi area for these
- and there is again a rectangular side with width 9 m and length 10 m so you need calculi again area of this too

- after you get these areas you need just adding and will get the right answer

- hope so much that you know formula for area of a right triangle and formula for area of a rectangle

so good luck
