$Perimeter=\frac{5x-16}{2}$

EXPLANATION

Let w=x represent the width of the rectangle.

One-fourth of the width will be,

$\frac{1}{4}x$

Let represent the length of the rectangle.

Then, subtracting 4 units from one-fourth the width gives us the length

$\Rightarrow l=\frac{1}{4}x-4$

Perimeter =2x+2l

$\Rightarrow Perimeter=2x+2(\frac{1}{4}x-4)$

We expand to obtain;

$Perimeter=2x+\frac{x}{2}-8$

$Perimeter=\frac{x+4x-16}{2}$

$Perimeter=\frac{5x-16}{2}$

a. How can I solve the equation for a ?
.
Lemme try ..
F = ma
a = F/m
Did u meant this ?
.
b. The units for force is not mentioned , therefore , I can't solve it. Either mass or force should've been mentioned ..
.
c.
F = ma
25 = m5
25/5 = m
5 = m
