The width of a rectangle is the length minus 6 units. The area of the rectangle is 7 units. What is the length, in units, of the rectangle?.

Sagot :

The length of the given rectangle is 7 units.

What is the area of the rectangle?

The area of the rectangle is the product of its length and width.

I.e., A = l × w sq. units

Calculation:

It is given that, the width of a rectangle is the length minus 6 units.

I.e., W = L - 6 units

Then, the area of the rectangle is

A = L × (L - 6)

But we have given that, the area of the rectangle is 7 sq. units.

So, we can write

7 = L² - 6L

⇒ L² - 6L - 7 = 0

⇒ L² - 7L + L - 7 = 0

⇒ L(L - 7) + 1(L - 7) = 0

⇒ (L + 1)(L - 7) = 0

∴ L = -1 or L = 7

The length should not be a negative value. So, the length of the given rectangle is 7 units.

Then, the width of the rectangle is

W = L - 6 = 7 - 6 = 1 unit.
