Step-by-step explanation:

19) length 22

perimeter= 120

20) side =23

Answer 2

Answer:

length = 22cm

& if the length is doubled then the perimeter is 120cm

Step-by-step explanation:

perimeter of rectangle = 2 ( L + B )

76 = 2 ( L + 16)

76/2 = L + 16

38 - 16 = L

22 cm = L

=> if the length is doubled then the

perimeter = 2(L + B)

= 2 ( 44+16)

= 2×60

= 120 cm
