Question

A rectangle has a width w that is 5 units longer than its length l. Which equation expresses the rectangle's area, A?

Answer 1

A = L(5+L)
In order to solve the equation, you need to know the value of the length

Answer 2

Answer: The rectangle's area is expressed as $l^2+5l$

Step-by-step explanation:

Since we have given that

Let the length of rectangle be 'l'.

Let the width of rectangle be 'l+5'.

We need to find the area of rectangle :

As we know the formula for "Area of rectangle ":

$Area=length\times breadth\\\\Area=l(l+5)\\\\Area=l^2+5l$

Hence, the rectangle's area is expressed as $l^2+5l$
