There is more than one way to answer math questions. So, by giving many tutors the chance to reply, you may find a method that is to your liking.
I will do 2 questions only.
(1) How many square yards of linoleum are needed for a kitchen floor that measures 10 ft by 12 ft?
To answer this question, we need to convert feet to yards.
10 feet times 12 feet = 120 feet.
How many yards in 120 feet?
There are 3 feet in one yard.
So, 120 feet divided by 3 feet = 40.
The answer is 40 yards.
==================================================

(2) Find the area of a square whose perimeter is 7.2 m.
A square has equal measure on each side.
A square has 4 sides.
We are given the perimeter to be 7.2 meters.
To find one side, we divide 7.2 by 4.
Side of this square = 7.2/4
Side of this square = 1.8 meters.
We now use the formula for the area of a square, which is Area = side squared or in short A = s^2.
We plug 1.8 for s, square it and there is your area.
A = (1.8)^2
A = 1.8 times 1.8
A = 3.24 meters^2
The little 2 after the word "meters" indicates that I found the area because area is always measured in square units.
