Answer:
The length of the rectangle = 63 ft
Step-by-step explanation:
Let us assume the width of the rectangle = m ft
So, the length of the rectangle = 3 x Width = 3 x m = 3 m ft
Perimeter = 168 ft
PERIMETER OF A RECTANGLE = 2 (LENGTH + WIDTH)
⇒ 168 ft = 2 ( 3 m + m)
or, 168 = 2 ( 4 m)
or, 8 m = 168
⇒ m = 168/8 = 21
or, m = 21 ft
Hence, the width of the rectangle = m = 21 ft
And the length of the rectangle = 3 x m = 3 x 21 = 63 ft
