Question

NEED HELP ASAP!!

Answer 1

84 square inches divided by 14 inches equals 6

84 divided by 14 = s

Answer 2

Alright, lets get started.

Two sides of the rectange are 14 and s.

So, the area of the rectange would be = $length * width$

So, the area of the rectange would be = $14 s$

A triangle is cut from the rectangle.

The height of the triangle is = $\frac{s}{2}$

The base of the triangle is = 14

So area of the triangle would be = $\frac{1}{2} *base * height$

area of the triangle would be = $\frac{1}{2} * 14*\frac{s}{2}$

area of the triangle would be = $\frac{7s}{2}$

So, the area of shaded region = area of rectange - area of triangle

the area of shaded region = $14 s -\frac{7s}{2}$

As per given in question, area of shaded region is 84, hence

$14 s -\frac{7s}{2} = 84$..........equation

So, this is the equation for s : Answer
