Solution 1.

Area of rectangle = l×b

Where, l = 7.5cm

And, b = 3.6cm.

Area of rectangle = l×b

=> 7.5×3.6

=> 27cm^2

Perimeter of rectangle = 2(l+b)

=> 2(7.5+3.6)

=> 2(11.1)

=> 22.2cm^2

Solution 2.

Perimeter of rectangle = 2(l+b)

=> 36 = 2(l+8.4)

=> 36/2 = l+8.4

=> 18 = l+8.4

=> 18-8.4 = l

=> Length = 9.6cm.

Area of rectangle = l×b

=> 9.6×8.4

=> 80.64
