Question

19.The perimeter of a rectangle is 16cm and its width is 3.5 cm.Find its length.​

Answer 1

Answer:

Answer is 4.5 cm

Step-by-step explanation:

let, the measure of length be x

Perimeter of rectangle= 2(l+b)

                       16 = 2(x+3.5)

                       16= 2x+ 7

                      16- 7=2x

                     9 =2x

                      X=9/2

                     X= 4.5 cm

Hence, length is 4.5 cm.
