What is an algebraic expression to find the number of squares in the border of a 75x75 grid?

Well, if the grip is 75 x 75, you can rule out that the grid is 75 squares in each border.

Step-by-step explanation:

75 x 75 = a x b

a= horizontal side lengths

b= vertical side lengths

Rule that a= 75 squares and b= 75 squares.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

the correct answer would be:

220 centimeters

to get this you can use the pythagorean theorem
