Answer:
179 square meters
Step-by-step explanation:
you can look at the figure into 3 different rectangles. 2*7=14, 2*6=12, 17*9=153. 14+12+153=179.
For 49 It's 4*12 and 2*24 and 1*48 and for 64 it's 8*8 and 2*32
Probability(error in one block)= 1/5
<span>Probability(error in 3 blocks)= 3*(1/5)= 0.6</span>
Let,
0 = No error
<span> 1 = error
</span>Hence.
E(x) = 0.4 x 0 x+0.6 + 1
= 1.6
