A rectangle has length x width of 21 x 5 Calculate the perimeter and area
Calculate Area (A):
A = l x w where l = length and w = width Plug in l = 21 and w = 5 A = 21 x 5 A = 105
Calculate Perimeter (P):
P = 2(l + w) where l = length and w = width Plug in l = 21 and w = 5 P = 2 * (21 + 5) P = 2 * 26 P = 52
Calculate diagonal length
Diagonal = √l2 + w2 where l = length and w = width Plug in l = 21 and w = 5 Diagonal = √212 + 52 Diagonal = √441 + 25 Diagonal = √466 Diagonal = 21.587033144923
Calculate the circumradius R:
R =
√l2 + w2

R =
√212 + 52

Calculate the inradius r:
r =
lw
l + w
r =
(21)(5)
21 + 5
r =

r = 4.0384615384615
Other Properties:
Faces = 1 Edges = 4 Vertices = 4
Final Answers
l = 21 w = 5 A = 105 P = 52 Diagonal = 21.587033144923 R = 10.793516572461 r = 4.0384615384615 Faces = 1 Edges = 4 Vertices = 4
What is the Answer?
l = 21 w = 5 A = 105 P = 52 Diagonal = 21.587033144923 R = 10.793516572461 r = 4.0384615384615 Faces = 1 Edges = 4 Vertices = 4
