Question

Ahmed owns a land of breadth (x+7) units &having an area of 2+ 14x + 49 sq. Units. (i)Find its length.

Answer 1

Answer:

l = (x+7) units

Step-by-step explanation:

Given that,

Breadth of the rectangle, b = (x+7) units

Area of the rectangle, $A=x^2+14x+49$

The area of a rectangle is given by :

$A=lb\\\\l=\dfrac{A}{b}\\\\l=\dfrac{(x^2+14x+49)}{(x+7)}\\\\l=\dfrac{(x+7)^2}{(x+7)}\\\\l=(x+7)\ \text{units}$

So, the length of the land is (x+7) units.
