Areas of paralleolgrams and triangles?

Mathematics
1 answer:
lapo4ka [179]3 years ago

The area of parallelogram is

A=base\cdot height.

If base has length 9.9 in and height has length 5.5 in, then the area is A=9.9\cdot 5.5=54.45 sq. in.

When base has length 11 in and height is unknown h, then A=11\cdot h.

Since the area is 54.45 sq. in., then

54.45=11h,\\ \\ h=\dfrac{54.45}{11} =4.95 in.

Answer: h=4.95 in.

Your scaling in the x direction is OK, but you didn't scale in the y direction properly. Hint. Scale each vertex of the original rectangle independently to construct the scaled rectangle.
I see the original points and their scaling by 2 as
(2,2) - Scales to (2*2, 2*2) = (4,4) OK in your drawing.
(-2,2) - Scales to (-2*2, 2*2) = (-4,4) OK in your drawing.
(2,5) - Scales to (2*2, 5*2) = (4,10) Error in your drawing.
(-2,5) - Scales to (-2*2, 5*2) = (-4,10) Error in your drawing.
