HELP ME

A rectangle is 4 meters wide and 14 meters long. What is the perimeter of the rectangle?
36 meters
72 meters
18 meters
56 meters

36 meters

Step-by-step explanation:

The perimeter of a rectangle can be found using:

1. p=l+l+w+w

or

2. p=2l+2w

The rectangle has a width of 4 meters and a length of 14 meters. Substitute 4 in for w and 14 in for l.

1. p=l+l+w+w

p=14+14+4+4

Add all the numbers together

p=28+8

p=36

2. p=2l+2w  

p=2(14)+2(4)

Multiply 2 and 14

p=28+2(4)

Multiply 2 and 4

p=28+8

Add 28 and 8

p=36

The perimeter of the rectangle is 36 meters

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!
