Answer:
Step-by-step explanation:
We know the perimeter of a triangle is the sum of all the sides( two legs and one hypotenuse).
By pythagoras we know that
and the perimeter is 
.
Since P=24 and a=6 we have these equations:
From the last equation we have 
. Replace h in the first equation we get that
and h=18-8=10
When you turn 90 degrees from north-west you would be in south-west direction. Then, south-east will be in your 90 degrees left.
The answer is 488.
22*17=374
12*19=228
228/2=114
374+114=488
68 + (x / 54) = 72 68 + (x / 54) • 54 = 72 • 54 68 + x = 72 • 54 68 + x = 3,888 68 + x - 68 = 3,888 - 68 x = 3,888 - 68 x = 3,820 I'm pretty sure this is right. Good luck!
