Question

find the perimeter and area of the following rectangle length 12 centimetre 8
breadth its ​

Answer 1

Answer:

perimeter= 2(l+b)

= 2(12+8) = 2 × 20 = 40cm^2

area = l× b = 12 × 8 = 96cm^2

Answer 2

Answer:

Given ,

Length = 12cm

Breadth = 8cm

Perimeter of rectangle formula = 2(l+b)

= 2(12+8)

= 2(20)

= 40

Therefore, perimeter of rectangle is 40cm.

Area of rectangle = l×b

= 12×8

= 96cm^2.

Therefore, area of rectangle = 96 cm^2.
