Step-by-step explanation:
Answer:
978 in^2
Step-by-step explanation:
the area of the rectangle:
24in X 30in = 720 in^2
the area of the two similar triangles:
12 X 9 / 2 + 12 X 9 / 2 = 108 in^2
the area of the last triangle:
20 in X 15 in /2 = 150in^2
.
the total area is the sum of the areas:
720in^2 + 108in^2 + 150in^2 = 978in^2.
Answer:
3n + 75
Step-by-step explanation:
Multiply n by 3 = 3n
Multiply 25 by 3 = 75
3/11 divided by 9/13 = 3/11 multiplied by 13/9 = 39/99=13/33
