Enter 2 values below
A rectangle has length x width of 3 x 5
Calculate the perimeter and area
Calculate Area (A):
A = l x w
where l = length and w = width
Plug in l = 3 and w = 5
A = 3 x 5
A = 15
Calculate Perimeter (P):
P = 2(l + w)
where l = length and w = width
Plug in l = 3 and w = 5
P = 2 * (3 + 5)
P = 2 * 8
P = 16
Calculate diagonal length
Diagonal = √l2 + w2
where l = length and w = width
Plug in l = 3 and w = 5
Diagonal = √32 + 52
Diagonal = √9 + 25
Diagonal = √34
Diagonal = 5.8309518948453
Calculate the circumradius R:
| R = | √l2 + w2 |
| 2 |
| R = | √32 + 52 |
| 2 |
| R = | √9 + 25 |
| 2 |
| R = | √34 |
| 2 |
| R = | 5.8309518948453 |
| 2 |
R = 2.9154759474227
| r = | 15 |
| 8 |
Calculate the inradius r:
| r = | lw |
| l + w |
| r = | (3)(5) |
| 3 + 5 |
| r = | 15 |
| 8 |
r = 1.875
Other Properties:
Faces = 1
Edges = 4
Vertices = 4
