Perimeter is 100 meters length is 12 m more than width what is length and width

Perimeter of rectangle = 2(l+w)

let. width = x, length = x+12

So, 100 = 2(x+x+12)

100=2(2x+12)

100=4x+24

4x=76

x=19, y=19+12 = 31

So, Length = 31 m & Width = 19 m

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!

positive

the quadrant is facing upwards
