↓Steps Explained:↓



A rectangle has length of 3 and perimeter of 50

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

w = 22>

w  =  P - 2l
  2

w  =  50 - 2(3)
  2

w  =  50 - 6
  2

w  =  44
  2

Calculate Area (A):

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

Plug in l = 3 and w = 22

A = 3 x 22

A = 66

Calculate diagonal length

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

Plug in l = 3 and w = 22

Diagonal = √32 + 222

Diagonal = √9 + 484

Diagonal = √493

Diagonal = 22.203603311175

Calculate the circumradius R:

R  =  √l2 + w2
  2

R  =  √32 + 222
  2

R  =  √9 + 484
  2

R  =  √493
  2

R  =  22.203603311175
  2

R = 11.101801655587

Calculate the inradius r:

r  =  lw
  l + w

r  =  (3)(22)
  3 + 22

r  =  66
  25

r = 2.64

Other Properties:

Faces = 1

Edges = 4

Vertices = 4
