Question

The length and breadth of a rectangle are
represented by (3x10y5)-2 and (5x-7yº)-1. Find
the expression which represents the area of th
rectangle.​

Answer 1

Step-by-step explanation:

The area & perimeter in the form of algebraic expression.are respectively.

$3x {}^2 + 12x + 9x \: nd \: 6x + 12x$

Length of r rectangle = 3x +3

Breadth of rectangle = x +3

We use the formula

Area of rectangle °= Length × Breadth

Area of rectangle =

$(3x + 3)(x + 3) = 3x {}^2{} + 9x + 3x + 9 = 3x {}^2{} + 12x + 9$

Perimeter of rectangle = 2( l + b ) =

$2(2x + 3 + x + 3) = 2(3x + 6) = 6x + 12$

Hence the area and perimeter in the form of algebraic expression. are 3x² + 12x +9 & 6x + 12 respectively.
