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 = √l2 + w2 where l = length and w = width Plug in l = 4 and w = 3 Diagonal = √42 + 32 Diagonal = √16 + 9 Diagonal = √25 Diagonal = 5
Calculate the circumradius R:
R =
√l2 + w2

R =
√42 + 32

Calculate the inradius r:
r =
lw
l + w
r =
(4)(3)
4 + 3
r =
12

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
What is the Answer?
l = 4 w = 3 A = 12 P = 14 Diagonal = 5 R = 2.5 r = 1.7142857142857 Faces = 1 Edges = 4 Vertices = 4
