Question

The length of a rectangle is (4x+1)m and its breadth is (3x+2)m. Let's calculate the area of the rectangle.​

Answer 1

Answer:

area of rectangle=length*breadth

=4x(3x+2)+1(3x+2)

=12x^2+8x+3x+2

=12x^2+11x+2  is the area in metre^2

Step-by-step explanation:

Answer 2

Question :-

The length of a rectangle is (4x + 1) m and it's breadth is (3x + 2) m. Let's calculate the area of the rectangle.

Answer :-

Given -

• length = ( 4x + 1 ) m
• breadth = ( 3x + 2 ) m

To Find -

• Area

Solution -

area of the rectangle

= length × breadth

= (4x + 1) m × (3x + 2) m

= (4x + 1)(3x + 2) m²

= [ 4x(3x + 2) + 1(3x + 2) ] m²

= [ 4x(3x) + 4x(2) + 1(3x) + 1(2) ] m²

= [ 12x² + 8x + 3x + 2 ] m²

= [ 12x² + 11x + 2 ] m²

____________

Hence, the area of the rectangle will be

(12x² + 11x + 2) m².
