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

l = (x+7) units

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=(A)/(b)\\\\l=((x^2+14x+49))/((x+7))\\\\l=((x+7)^2)/((x+7))\\\\l=(x+7)\ \text{units}`

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