Answer 1

OD. 15 inches

Explanation:

Formula for Perimeter of rectangle is given as:

`P = 2(l + w) \\ \therefore \: 50 = 2(l + 10) \\ \therefore \: (50)/(2) = (l + 10) \\ \therefore \: 25 = (l + 10) \\ \therefore \:l = 25 - 10 \\ \therefore \:l = 15 \: inches`

Answer 2

the answer is 15inches

Explanation:

if the width is 10 inches and it is a rectangle it will have two sets of parallel lines and so you would do 50-20=30 and the 30 would be divided by 2 to give 15

`50-20=30\\30/2=15`
