*The side with the middle length is 12cm, therefore BC must be 12 cm
------------------------------------------------------------<span> Ratio ------------------------</span>---------------------------------<span>-- BC:AC:AB 4 : 3 : 5
</span>----------------------------------------------------------- <span>Find 1 share </span>-----------------------------------------------------------<span> Given that BC = 12 cm 4 shares = 12 cm 1 share = 12 ÷ 4 = 3cm
</span>----------------------------------------------------------- Find AC (4 shares) -----------------------------------------------------------<span> 3 shares = 3 x 3 = 9 cm BC = 9cm
</span>----------------------------------------------------------- <span>Find AB (5 shares) </span>-----------------------------------------------------------<span> 5 shares = 5 x 3 = 15cm AB = 15cm
</span>------------------------------------------------------------ Length ----------------------------------------------------------- BC : AC : AB 12cm : 9cm : 15cm<span>
</span>------------------------------------------------------------------ <span>Answer: The perimeter is 36cm </span>------------------------------------------------------------------<span>
</span>------------------------------------------------------------------ <span>Area </span>------------------------------------------------------------------ 1/2 x 9 x 12 = 54cm²<span>
</span>------------------------------------------------------------------ Answer: Area = 54cm² ------------------------------------------------------------------<span>
Given that the biggest ratio is AB </span>⇒AB is the hypotenuse AB = 15 cm
------------------------------------------------------------------ Answer: Hypotenuse = AB = 15cm ------------------------------------------------------------------
The interquartile range is from Q1 to Q3 and to get this you have to subtract Q2 by Q3. The 10 units represent that only 10 units are fit in the given range.
