Answer:
sorry this is for the points
The area of the triangle is
a=( m x n) /2 in cm² , implies 2xa = m xn
the area of the rectanglle
A= n x m in cm²
but we know <span> 2xa = m xn = A, </span>
that means the surface of the rectangle is 2 times of the area of the triangle
We have to use the following formula which is

Given values of F and m are 7.92 Newtons and 3.6 kilograms .
Substituting these values in the formula, we will get

To solve for a, we have to divide both sides by 3.6 that is

And that's the required answer .
Umm, what grade are you in . i’ll see if i can help
The answer is 2
Add like terms
Add 8 to -8 and the zero
To get 4x=8
Then divide 4 and 8 by 4
To get x=2
