Question

The length of a rectangle is 6 meters more than its width. If the area of the rectangle is 135 square meters, find its dimensions.

Answer 1

wait so is it x+6 or x2+6x

Answer 2

I'm a little confused sorry

Answer 3

hold on

Answer 4

\(2L+2W=135\\L=6+W\\2(6+W)+2W=135\)

Answer 5

w x w + 6 = 135 w2 + 6w - 135 =0 Ie (w - 9)(w + 15) = 0 width = 9m (length = 15m)

Answer 6

now distribute

\(2(6+W)\)

Answer 7

Now I'm really confused. I don't understand this at all

Answer 8

do you know distribution?

Answer 9

Not really. Could you explain please?

Answer 10

\(\Large{a(b+c)=a*b+a*c}\)


Multiply what's on the outside with everything on the inside.

Answer 11

@trisha001 can you do it now?

Answer 12

so I solve a*b+a*c first? and multiply it with a(b+c) ?

Answer 13

no

you multiply a(b+c) which gives you a*b + a*c

do that with 2(6+W)

Answer 14

so now I multiply 2(6+w) a(b+c) or 2(6+w) and a*b+a*c

Answer 15

I'm sorry for being so confused

Answer 16

a(b+c) was just an example '-'

2(6+W) = 2*6 + 2*W

Answer 17

@Serenity74

Answer 18

alright sorry

Answer 19

when I did the problem I got 0=0 is that correct?

Answer 20

???

Answer 21

2(6+W) = 2*6 + 2*W

Answer 22

2*6 = ?
