The length of a rectangle is equal to triple the width. if the perimeter is equal to 168 feet ,what is the length of the rectangle.

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

answer:

a=9

step-by-step explanation: lmk if you need a explanation

answer: h=5.6 i don't really know how to put into words, so i though i would let you do that. i hope i was able to some

step-by-step explanation:

18 = 6(h)+1/2

18 = 6h+1/2

18-1 = 6h/2

17 = 3h

17/3 = h

h = 5.6
