Question

The area of each mat is 135 square inches.the width of each place mat is 9 inches.how many inches long are all the sides of the place mat?

Answer 1

Answer:15inches long

Step-by-step explanation:

so the area of the mat assuming its a square will be

Area=Length*Width for the working to be

135=l*9(where L represents the length)

so it will come to 135=9L

divide both sides by 9 to get the value of L which is 15L

this means that all the other mats have a length of 15inches.
