The perimeter of a rectangle is 150 cm. the length is 15 cm greater than the width. find the dimensions

Length = 45 cm , Width = 30 cm .

Step-by-step explanation:

Given  : The Perimeter of a rectangle is 150 cm. The length is 15 cm greater than the width.

To find : Find the dimensions.

Solution : We have given

Perimeter of rectangle = 150 cm .

Length is 15 cm greater than the width.

Length = 15 + width .

Formula of perimeter = 2 ( length + width ) .

Plugging the values .

150 = 2 ( width + 15 + width ) .

150 = 2 ( 15 +  2 width ) .

On dividing both sides by 2.

75 = 15 + 2 width .

On subtracting both sides by 15 .

75 - 15 = 2 width .

60 = 2 width.

On dividing both sides by 2.

30 cm = width .

Length =  15 + 30 .

Length =  45 cm

Therefore, Length = 45 cm , Width = 30 cm .

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
