Answer:45cm
Explanation: If the whole paper is 12 by 15 you have to divide them both by 2!
12 divide by 2=6
15 divide by 2=7.5
Then you have to multiply them together to find the area.
6x7.5=45
So therefore the answer is 45cm.
Answer:
Not on there but it is 76in2
Step-by-step explanation:
Starting with the trapezoid. We know that a trapezoid can be split into 2 triangles and 1 rectangle. So the area of the trapezoid will be 4+32+4 which is 40 now that we know the trapezoid's area we can find the rectangle's area. The rectangle's area will be 12x3 which is 36. So, you would add both:40+36= 76in2.
The answer is 9 I am so smart XD
How you durin is the answer because it makes the most since
