Question

Find the perimeter of:
(1) Rectangle ABCD, given that AB = 4.2 cm and BC = 3.8 cm.​

Answer 1

Answer: 16cm

Step-by-step explanation: 2(l+b)

                                            2(4.2+3.8)

                                            2 x 8

                                            16cm

Answer 2

Sides of rectangle ( AB & BC ) = 4.2 & 3.8 cm respectively.

Let AB be taken as LENGTH and BC be taken as BREADTH.

Since, the perimeter of rectangle = 2 ( l + b )

Therefore, perimeter of ABCD = 2 ( 4.2 + 3.8 ) cm

= 2 * 8.0 cm = 16 cm

I Hope this helps uhhh.... ✌️
