Brainliest for the correct answer :)

The Area of Shaded region is equal to the difference in Area of rectangle and Area of triangle .

let's solve for area of rectangle :

Now, Area of Triangle :

So, the area of the shaded region in terms of x :

And since, Area of Shaded region = 44 cm²

By equating the area, we get

Value of x = 2

step-by-step explanation:

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
