The length of a rectangle is 9cm less than three times the width. If the perimeter is 38cm, what is the length and width of the rectangle?

Step-by-step explanation:

Hey there!

Let the width be x. Then the length will be 3x - 7.

Perimeter (p) = 38cm.

We have;

Perimeter (p)= 2(length+wide)

38 = 2(3x-9+x)

38 = 8x - 18

38+18 = 8x

X = 56/8

Therefore, x = 7cm

3x-9 = 3*7-9

= 12cm.

Therefore, wide= 7cm and length= 12cm.

Hope it helps...

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23

the answer is 24
