Answer 2

Step-by-step explanation:

area of rectangular box = area of tape

let length of tape = X cm.

Area of tape = 17X

Area of rectangular box = 50*30 = 1500

17x = 1500

x = 1500/17

x = 88.23

length of tape = 88 cm + .23 cm

1 cm. = 10 mm

0.23 cm. = 2.3 mm

length of tape used = 88 cm + 2.3 mm

length of tape used =88cm + 2.3 mm
