The length of a rectangle is 6 inches more than 3 times the width. the perimeter is 100 inches. find the length and the width.

length = 39 inches

width = 11 inches

Step-by-step explanation:

Assuming the length of the rectangle to be l and width to be w, we can write the length as:

We know that perimeter of the rectangle is 100 inches and its formula is:

Perimeter of a Rectangle = 2l + 2w

So substituting the given values in the above formula:

Substituting this value of w to find the length l:

Therefore, the length = 39 inches and width = 11 inches.

The width is 11 inches

The length is 39 inches

Step-by-step explanation:

Length of a rectangle is 6 inches more than 3 times the width

l= 3w+6

Perimeter is 100 inches

P = 2(l+w)

100 = 2(l+w)

Substitute in for l

100 =2(3w+6 +w)

Combine like terms

100 =2(4w+6)

Divide each side by 2

100/2 = 2/2 (4w+6)

50 = 4w+6

Subtract 6 from each side

50-6 =4w+6-6

44 = 4w

Divide by 4

44/4 = 4w/4

11 =4

The width is 11 inches

Now we need to find the length

l= 3w+6

l= 3(11)+6

l = 33+6

l = 39 inches

x= 149. 24+7=31. 180-31=149
