Enter 2 values below

<-- Length
<-- Width
<-- Area
<-- Perimeter
  

A rectangle has length of 52 and perimeter of 162

Calculate the width and area

Perimeter of a rectangle

P = 2(l x w)

Multiply the 2 through

P = 2l + 2w

Subtracting 2l from each side

P - 2l = 2w

Divide each side by 2

P - 2l
2
=
  
2w
2

w  =  P - 2l
  2

w  =  162 - 2(52)
  2

w  =  162 - 104
  2

w  =  58
  2

w = 29>

Calculate Area (A):

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

Plug in l = 52 and w = 29

A = 52 x 29

A = 1508

Calculate diagonal length

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

Plug in l = 52 and w = 29

Diagonal = √522 + 292

Diagonal = √2704 + 841

Diagonal = √3545

Diagonal = 59.539902586417

Calculate the circumradius R:

R  =  l2 + w2
  2

R  =  522 + 292
  2

R  =  2704 + 841
  2

R  =  3545
  2

R  =  59.539902586417
  2

R = 29.769951293208

r  =  1508
  81

Calculate the inradius r:

r  =  lw
  l + w

r  =  (52)(29)
  52 + 29

r  =  1508
  81

r = 18.617283950617

Other Properties:

Faces = 1

Edges = 4

Vertices = 4
