what question is being asked
Is my answer right? Also, if not is my triangle formula wrong?
Can't tell if ans. is right if I don't know the question.
Composite figure finding area.
A=22cm x 17cm = 374 area of rectangle
(Long side is 22cm, Width is 17cm.)
A = 1/2 x b x h
A = 1/2 x 19cm ( no height given)
A= 9.5 area of Triangle
I added 323.5cm + 9.5cm = 333cm area of the composite figure.
Is the the right answer 333cm area of the composite figure?
If no height is given for the triangle, you cannot find the area. Does the triangle share a side with the rectangle? Could it be that the height of the triangle is one of the sides of the rectangle?
Your area for the rectangle is correct.
Sorry I added 374.5 (actual calculation of rectangle area) to 9.5 = 384cm total area of the composite figure is what I meant to type.
Yes I see what your saying. The bottom of the triangle though is apart of the side of the rectangle. But just a small portion of it. I knew my triangle something was off.
A = 1/2 x 10cm???x 19cm
The rectangle 10cm is paraelle to 22cm.
I think I figured it out. The triangle.
A= 1/2 x bxh
A = 1/2 x 19 x 12 = 114cm area of for Triangle.
I got the 12 because the paraelel side of 10 is 22 of the rectangle. So the triangle looks like (attached to rect.) it is 12cm.
