Question

Tezium is 84.5 square centimetre and its height is 6.5 CM if one of its parallel side is 15.2 cm long ,what is the length of the other sude​

Answer 1

Answer:

10.8 cm

Step-by-step explanation:

Area = 1/2 x height (sum of parallel sides)

⇒84.5 = 1/2 x 6.5 (15.2 + x)         where x is unknown side

⇒84.5/6.5 = 1/2 (15.2 + x)

⇒13 x 2 = 15.2 + x

⇒26 = 15.2 + x

⇒x = 26 - 15.2

∴x = 10.8 cm
