<-- Area
<-- Perimeter
  

A rectangle has length x width of 10 x 5

Calculate the perimeter and area

Calculate Area (A):

A = l x w
where l = length and w = width

Plug in l = 10 and w = 5

A = 10 x 5

A = 50

Calculate Perimeter (P):

P = 2(l + w)
where l = length and w = width

Plug in l = 10 and w = 5

P = 2 * (10 + 5)

P = 2 * 15

P = 30

Calculate diagonal length

Diagonal = √l2 + w2
where l = length and w = width

Plug in l = 10 and w = 5

Diagonal = √102 + 52

Diagonal = √100 + 25

Diagonal = √125

Diagonal = 11.180339887499

Calculate the circumradius R:

R  =  l2 + w2
  2

R  =  102 + 52
  2

R  =  100 + 25
  2

R  =  125

R = 5.5901699437495

r  =  50
  15

Calculate the inradius r:

r  =  lw
  l + w

r  =  (10)(5)
  10 + 5

r  =  50
  15

r = 3.3333333333333

Other Properties:

Faces = 1

Edges = 4

Vertices = 4
