Enter 2 values below
A rectangle has length of 3 and perimeter of 50
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 = | 50 - 2(3) |
| 2 |
| w = | 50 - 6 |
| 2 |
| w = | 44 |
| 2 |
w = 22>
Calculate Area (A):
A = l x w
where l = length and w = width
Plug in l = 3 and w = 22
A = 3 x 22
A = 66
Calculate diagonal length
Diagonal = √l2 + w2
where l = length and w = width
Plug in l = 3 and w = 22
Diagonal = √32 + 222
Diagonal = √9 + 484
Diagonal = √493
Diagonal = 22.203603311175
Calculate the circumradius R:
| R = | √l2 + w2 |
| 2 |
| R = | √32 + 222 |
| 2 |
| R = | √9 + 484 |
| 2 |
| R = | √493 |
| 2 |
| R = | 22.203603311175 |
| 2 |
R = 11.101801655587
| r = | 66 |
| 25 |
Calculate the inradius r:
| r = | lw |
| l + w |
| r = | (3)(22) |
| 3 + 22 |
| r = | 66 |
| 25 |
r = 2.64
Other Properties:
Faces = 1
Edges = 4
Vertices = 4
