Find the perimeter of rectangle whose length is 40 and the diagonal is 41 cm<br>​
Bond [772]

Answer:

<h2>              P = 98 cm</h2>

Step-by-step explanation:

Given one side and diagonal of rectangle we can use Pythagorean theorem to calculate the other side of it.

L=40\, cm\\D=41\,cm\\W=\ ?\\\\W^2+L^2=D^2\\\\W^2+40^2=41^2\\\\W^2+1600=1681\\\\W^2=81\\\\W=9

Perimeter:

P = 2W + 2L = 2•40 + 2•9 = 80 + 18 = 98

Help me with this please!!!!!!!!!
IrinaVladis [17]

Answer:

d = 17.58

Step-by-step explanation:

d = √(x2 - x1)^2 + (y2 - y1)^2 + (z2 - z1)^2

P1(0, 0, 0) P2(8, 7, 14)

Substitute the values in the above equation and you will get

d = √(8 - 0)^2 + (7 - 0)^2 + (14 - 0)^2

= √(64 + 49 + 196)

= √309

= 17.58
