Answer:
l = 88 and b = 22
Step-by-step explanation:
Perimeter of a rectangular atrium = 220 inches
Length of atrium = [tex]4 \times (width\ of\ atrium)[/tex]
Now, let the width of atrium be x
∴ Length of atrium = 4x.
Perimeter of rectangular atrium = 2 (l + b)
2(l + b) = 220
2 (4x + x) = 220
2 (5x) = 220
10x = 220
x = 22
So the width of rectangular atrium = 22
∴ length of rectangular atrium = 4x = 4 (22) = 88
