Can someone help me the area is 176cm squared and the perimeter 60cm
----
Perimeter = 2(L + W)
60 = 2(L+W)
L + W = 30
-----
Area = L*W
176 = L*W
===================
L = 30-W
Substitute for "L" and solve for "W":
176 = (30-W)W
---
-W^2 + 30W - 176 = 0
W^2 -30W + 176 = 0
---
(W-22)(W - 8) = 0
-----
If Width = 22 then L = 8
If Width = 8 then Length = 22
-----------------------
