Question

The length of the rectangle is (2y+3)units and it's breadth is (2y-3) units. Find its area in terms of y. What will be the area if y= 30 units.​

Answer 1

Answer:

3591 cm ^2

Step-by-step explanation:

Length of rectangle = (2y+3)

Breadth of rectangle = (2y-3)

Area of rectangle = ?

Where y =30 units

Area of rectangle = length x breadth

Area of rectangle = (2y+3) (2y-3)

Where y =30 units

Area = (2(30) + 3) (2(30)-3)

Area = (60 +3) (60 -3)

Area = 63 x 57

Area = 3591 unis

Area of rectangle = 3591 units
