amanda is placing one foot square tiles and baseboard in a 10ft by 9ft room ignoring doorways how many ft of basebord does she need ? how many tiles does she need ?

is it 38

i think its 38 but i aslo think its 50

To calculate the amount of baseboard Amanda needs, we need to find the perimeter of the room since baseboard typically goes around the perimeter of the floor. The formula to find the perimeter of a rectangle is 2 * (length + width).

Given that the length of the room is 10ft and the width is 9ft, we can calculate the perimeter as follows:

Perimeter = 2 * (Length + Width)
= 2 * (10ft + 9ft)
= 2 * 19ft
= 38ft

So, Amanda needs 38 feet of baseboard for the room.

To find the number of tiles needed, we need to calculate the area of the room. The formula for the area of a rectangle is length * width.

Area = Length * Width
= 10ft * 9ft
= 90ft²

Since each tile covers an area of 1 square foot, Amanda will need 90 tiles to cover the entire room.

Perimeter = 2L + 2W

Can you take it from there?
I'll be glad to check your answer.

P = (2 * 10) + (2 * 9)

P = 20 + 18
P = 38 feet
