Answer:
its (B)
Step-by-step explanation:
Answer:
c = 7√2
Step-by-step explanation:
Apply pythagorean theorem to find the third side.
Thus, c² = a² + b²
where, c is the third side and a and b are the other sides.
Plug in the values
c² = 8² + (√34)²
c² = 64 + 34
c² = 98
c = √98
c = √(49 * 2)
c = 7√2
Answer:
either 3 or 64
Step-by-step explanation:
unable to process what I already know. 3 or 64
Answer:
840 cm
Step-by-step explanation:
Given that in the question we have, : 9, 1 cm × 1 cm squares setting a 3 × 3 grid.
Therefore wire required in 3 x 3 grid is
3(3+1) + 3(3+1)
= 3 × 4 + 3 × 4
= 24 I'm
Similarly, the length of the wire required in 20 by 20 grid will be
=> 20(20+1) + 20(20+1)
=> 20 × 21 + 20 × 21
=> 420 + 420
= 840cm
