Answer:
<h3>The expression for the perimeter P is

feet.</h3><h3> Area=49=lx square feet ( here

)</h3>
Step-by-step explanation:
Given that rectangle with height equals 4times width.
It can be written as

Let x be the width of the given rectangle
Therefore 


Rewritting the above equation we get

<h3>To write an expression for the perimeter P of the given rectangle :</h3>
Also given that area of the rectangle is 49 square feet.
Area=49 square feet.
We know area of rectangle = lw square units.
<h3>Therefore area=49=lx square feet ( here area=49 and w=

)</h3>
Rewritting we get
lx=49 square feet.


<h3>

feet</h3><h3>Perimeter P
