Enter 2 values below
A rectangle has length x width of 30 x 18
Calculate the perimeter and area
Calculate Area (A):
A = l x w
where l = length and w = width
Plug in l = 30 and w = 18
A = 30 x 18
A = 540
Calculate Perimeter (P):
P = 2(l + w)
where l = length and w = width
Plug in l = 30 and w = 18
P = 2 * (30 + 18)
P = 2 * 48
P = 96
Calculate diagonal length
Diagonal = √l2 + w2
where l = length and w = width
Plug in l = 30 and w = 18
Diagonal = √302 + 182
Diagonal = √900 + 324
Diagonal = √1224
Diagonal = 34.985711369072
Calculate the circumradius R:
| R = | √l2 + w2 |
| 2 |
| R = | √302 + 182 |
| 2 |
| R = | √900 + 324 |
| 2 |
| R = | √1224 |
| 2 |
| R = | 34.985711369072 |
| 2 |
R = 17.492855684536
| r = | 540 |
| 48 |
Calculate the inradius r:
| r = | lw |
| l + w |
| r = | (30)(18) |
| 30 + 18 |
| r = | 540 |
| 48 |
r = 11.25
Other Properties:
Faces = 1
Edges = 4
Vertices = 4
