A rectangle has length of 60 and area of 30
Calculate the width and perimeter
Area of a rectangle
A = l x w
Rearranging this formula, we get
| w = | A |
| l |
| w = | 1800 |
| 60 |
w = 30
Calculate Perimeter (P):
P = 2(l + w)
where l = length and w = width
Plug in l = 60 and w = 30
P = 2 * (60 + 30)
P = 2 * 90
P = 180
Calculate diagonal length
Diagonal = √l2 + w2
where l = length and w = width
Plug in l = 60 and w = 30
Diagonal = √602 + 302
Diagonal = √3600 + 900
Diagonal = √4500
Diagonal = 67.082039324994
Calculate the circumradius R:
| R = | √l2 + w2 |
| 2 |
| R = | √602 + 302 |
| 2 |
| R = | √3600 + 900 |
| 2 |
| R = | √4500 |
| 2 |
| R = | 67.082039324994 |
| 2 |
R = 33.541019662497
| r = | 1800 |
| 90 |
Calculate the inradius r:
| r = | lw |
| l + w |
| r = | (60)(30) |
| 60 + 30 |
| r = | 1800 |
| 90 |
r = 20

Faces = 1
Edges = 4
Vertices = 4
