10. Area= Base*Height
A=(3*5)/2
A=15/2
A=7.5 sq. cm.
200*7.5=1500
Hope this helps

15. the answer is 7.5 . There are 2 triangle shaped sides that meet that are each 3 centimeters and 5 centimeters long. The formula for finding the area of a triangle is A= 1/2 x bh (base times height). 5 is the base, so you set it up like this: 1/2 x 5 x 3. The answer to this formula is 7.5. There is your answer.
