Answer:
i can help with the area. so first find the area of the square. we know that one side is 10in long, to find the other side we must add 2+7+5=14. so now do 10 x 14 = 140. now since its a triangle we must split that in half which you get 70. are we done yet? NO! we have to subtract the square out of the triangle now. so the area of the square is 7 x 3 = 21. now we just subtract 70 - 21 = 49
your answer for area is 49in
