Answer 1

$\sf{\huge{\underline{\pink{Given :-}}}}$

• The dimensions of a given rectangle are (4x - 1)cm and (2x + 3)cm.

$\sf{\huge{\underline{\blue{To\:Find :-}}}}$

• The area of the rectangle.

$\sf{\huge{\underline{\purple{Answer :-}}}}$

We have,

• The length = (4x - 1) cm

• The breadth = (2x + 3) cm

We know, the area of rectangle = l × b

➝ (4x - 1) × (2x + 3)

➝ 8x² + 12x - 2x -3

➝ 8x² + 10x - 3

The area of the rectangle is 8x² + 10x - 3 .
