Answer 1

Answer:

the answer is 15inches

Step-by-step 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

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

Answer 2

Answer:

OD. 15 inches

Step-by-step explanation:

Formula for Perimeter of rectangle is given as:

$P = 2(l + w) \\ \therefore \: 50 = 2(l + 10) \\ \therefore \: \frac{50}{2} = (l + 10) \\ \therefore \: 25 = (l + 10) \\ \therefore \:l = 25 - 10 \\ \therefore \:l = 15 \: inches$
