Width = x
Length = x + 8
Solve x :
Given that the perimeter is 90:
*listing from the top lefthand corner, clockwise
(x) + (x + 8) + (x) + (8) + (x+8) + (x) + (x+8) + (x) + (8) + (x+8) = 90
8x + 48 = 90
8x = 42
x = 5.25
Find Length and Width :
Width = x = 5.25 cm
Length = 5.25 + 8 = 13.25 cm
Find Area :
4 rectangles = 5.25 x 13.25 x 4 = 278.25 cm²
Area = 278.25 cm²

Step-by-step explanation:
Using SOHCAHTOA
Where :
O =Opposite (across from a given angle,)
H = Hypotenuse (Longest side)
A = Adjacent ( next to a given angle.)
We can derive
Sin x = opposite/Hypotenuse
Cos x = Adjacent/ Hypotenuse
Tan x = Opposite/adjacent
