Enter 2 values below A rectangle has length x width of 4 x 3

Calculate the perimeter and area

Calculate Area (A):

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

Plug in l = 4 and w = 3

A = 4 x 3

A = 12

Calculate Perimeter (P):

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

Plug in l = 4 and w = 3

P = 2 * (4 + 3)

P = 2 * 7

P = 14

Calculate diagonal length

Diagonal = √l^{2} + w^{2} where l = length and w = width

Plug in l = 4 and w = 3

Diagonal = √4^{2} + 3^{2}

Diagonal = √16 + 9

Diagonal = √25

Diagonal = 5

Calculate the circumradius R:

R = 2.5

Calculate the inradius r:

r = 1.7142857142857

Other Properties:

Faces = 1

Edges = 4

Vertices = 4

Final Answers

l = 4 w = 3 A = 12 P = 14 Diagonal = 5 R = 2.5 r = 1.7142857142857 Faces = 1 Edges = 4 Vertices = 4
