Enter 2 values below
A rectangle has length of 505 and perimeter of 1520
Calculate the width and area
Perimeter of a rectangle
P = 2(l x w)
Multiply the 2 through
P = 2l + 2w
Subtracting 2l from each side
P - 2l = 2w
Divide each side by 2
| P - 2l | |
| 2 |
| = |
| 2w |
| 2 |
| w = | P - 2l |
| 2 |
| w = | 1520 - 2(505) |
| 2 |
| w = | 1520 - 1010 |
| 2 |
| w = | 510 |
| 2 |
w = 255>
Calculate Area (A):
A = l x w
where l = length and w = width
Plug in l = 505 and w = 255
A = 505 x 255
A = 128775
Calculate diagonal length
Diagonal = √l2 + w2
where l = length and w = width
Plug in l = 505 and w = 255
Diagonal = √5052 + 2552
Diagonal = √255025 + 65025
Diagonal = √320050
Diagonal = 565.72961739686
Calculate the circumradius R:
| R = | √l2 + w2 |
| 2 |
| R = | √5052 + 2552 |
| 2 |
| R = | √255025 + 65025 |
| 2 |
| R = | √320050 |
| 2 |
| R = | 565.72961739686 |
| 2 |
R = 282.86480869843
| r = | 128775 |
| 760 |
Calculate the inradius r:
| r = | lw |
| l + w |
| r = | (505)(255) |
| 505 + 255 |
| r = | 128775 |
| 760 |
r = 169.44078947368
