Question

If the length of a rectangle is x - 3 and the breadth is x - 5, what is the area of the rectangle?

Answer 1

A = x² - 8x + 15

Explanation:

the area (A) of a rectangle is calculated as

A = length × breadth

= (x - 3)(x - 5)

each term in the second factor is multiplied by each term in the first factor

x(x - 5) - 3(x - 5) ← distribute parenthesis

= x² - 5x - 3x + 15 ← collect like terms

= x² - 8x + 15

then A = x² - 8x + 15

Answer 2

`A=x^(2) -8x+15`.

Explanation:

A= L * B= (x-3)(x-5)= x^2-8x+15
