4) Area of parallelogram = b x h==> 36 x 24 =864
We can also find the area of the same parallelogram by taking as base the side that is equal to 27==> Area = 27 x h = 864 (since it's the same parallelogram)
27h = 864 & h = 864/27 = 32 (answer A)
5). It's the same logic and the same methodology and you will find 3.87 ≈ 3.9
