Question

length and breadth of rectangle are y+2 and y-2 what is the area of it
​

Answer 1

Answer:

Area = y² -4

Step-by-step explanation:

Area of rectangle = Length × Breadth

Length = y+2

Breadth = y-2

∴Area = (y+2)(y-2)

= y² - (2)²                        (using a²-b² formula)

= y² -4

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)
