Step-by-step explanation:

the lengths of any line (side, height,...) in A is twice as long as in B.

now, the area of a triangle is

baseline × height / 2

so, two lines are multiplied. that means the factor 2 gets multiplied in 2 times. and that means the area increases by the factor 2×2 = 4

therefore, the area of A is

40.5 × 4 = 162 cm²

Find the midpoint of the segment with the given endpoints. <br> ​(9​,9​) and ​(-1​,-3​)
katrin [286]

Answer is (4,3)

=============================

Add up the x coordinates to get 9+(-1) = 8. Divide this over two and we end up with 8/2 = 4

Repeat for the y coordinates: 9+(-3) = 6, which cuts in half to get 6/2 = 3

The midpoint is at (4,3)

-------

The midpoint formula is

\left(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}\right) where (x1,y1) and (x2,y2) are the endpoints.
