QUESTION ⁉️


please answer this question please ​

Answer 1

Answer:

Area= 2(l+b)

= 2(x+1+x+2)cm

= 2(2x+3)cm

= (4x+6)cm

Answer 2

Answer:

Question :-

If the length of the rectangle is (x+2) cm and breadth is (x+1) cm find the area of the rectangle

Required Answer :-

x²+x-2

Solution :-

Given :-

Length - (x+2) cm

Breadth - (x-1) cm

To find :-

The area of the rectangle

Formula used here :-

Area = length × breadth

Let's find the area !

$Area = l × b$

$= (x+2) × (x-1)$

$= x ( x-1) +2(x-1)$

$= x²-x +2x - 2$

$= {x}^{2} + x - 2$

Therefore area of the rectangle is x²+x-2
