Question

Area of a rectangle is (2 x+ 3)( x^2 − 4) sq. units . If length is (x − 2) units,then the breadth is​

Answer 1

Answer:

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

Step-by-step explanation:

Length of rectangle = 3x+3

Breadth of rectangle = x+3

Area of rectangle =

Area of rectangle =

Perimeter of rectangle =

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

Answer 2

Step-by-step explanation:

Area : 35y

2

+13y−12

Area of rectangle - Length×Breadth

35y

2

+28y−15y

35y

2

+28y−15y

7y(5y+4)−3(5y+4)

(7y−3)(5y+4)

∴ Length =(7y−3)

Breadth =(5y+4)
