Question

find the perimeter and area of the following :
length = 12cm , breadth = 8cm​

Answer 1

Answer:

Hence,

Perimeter = 40 cm

Area = 96 cm²

Step-by-step explanation:

Perimeter -

l = 12 cm

b = 8 cm

Perimeter of rectangle

= 2(l+b) units

= 2(12+8) cm

= 2×20 cm

= 40 cm

Area -

l = 12 cm

b = 8 cm

Area of rectangle

= l×b units²

= 12×8 cm²

= 96 cm²

Answer 2

Your answer:

Length of rectangle = 12 cm

Breadth of rectangle = 8 cm

Perimeter of rectangle = 2(l + b)

= 2(12 + 8)

= 2(20)

= 40 cm

Area of rectangle = l × b

= 12 × 8

= 96 cm²
