Question

11. What is the area of a rectangle whose length (2x+5) cm and width (x-1) cm?

Answer 1

Answer:

$A=2x^2+3x-5$

Step-by-step explanation:

Given that,

Length = (2x+5) cm

Width = (x-1) cm

We need to find the area of a rectangle. The formula for the area of rectangle is given by :

A = lb

$A=(2x+5)(x-1)\\\\=2x^2-2x+5x-5\\\\=2x^2+3x-5$

So, the required area is equal to $2x^2+3x-5$.
