A rectangle has length x width of 15.6 x 18.4
Calculate the perimeter and area
Calculate Area (A):
A = l x w
where l = length and w = width
Plug in l = 15.6 and w = 18.4
A = 15.6 x 18.4
A = 287.04
Calculate Perimeter (P):
P = 2(l + w)
where l = length and w = width
Plug in l = 15.6 and w = 18.4
P = 2 * (15.6 + 18.4)
P = 2 * 34
P = 68
Calculate diagonal length
Diagonal = √l2 + w2
where l = length and w = width
Plug in l = 15.6 and w = 18.4
Diagonal = √15.62 + 18.42
Diagonal = √243.36 + 338.56
Diagonal = √581.92
Diagonal = 24.123018053303
Calculate the circumradius R:
| R = | √l2 + w2 |
| 2 |
| R = | √15.62 + 18.42 |
| 2 |
| R = | √243.36 + 338.56 |
| 2 |
| R = | √581.92 |
| 2 |
| R = | 24.123018053303 |
| 2 |
R = 12.061509026652
| r = | 287.04 |
| 34 |
Calculate the inradius r:
| r = | lw |
| l + w |
| r = | (15.6)(18.4) |
| 15.6 + 18.4 |
| r = | 287.04 |
| 34 |
r = 8.4423529411765
