You can,
if you have a square with side 5
you can multiply 5*5=25
or you can add 5+5+5+5+5=25
If you want to do this just take one of the numbers and add it to itself the other numbers times.
so if you have 7*8
you add 7 to itself 8 times, so add 8 7's
7+7+7+7+7+7+7+7=56
or add 7 8's
8+8+8+8+8+8+8=56
Multiplying is much easier.
Area is length x width, so is not adding or taking away When you need to find the total of 2 areas, you have to add them
To find the lateral area of a cylinder, multiply the circumference (πd) by the height (πdh). After you have this, you can find the total surface area by adding twice the area of the base (2πr2).(Lateral area = πdh), (Surface area = πdh + 2πr2).
The perimeter is found by adding the length of each side. The area is found by multiplying the length of the square by the width.
Yes by working out individual sections and then adding them altogether.
By adding up all of the sides. To find the area, do base (bottem) X height X 1/2
Yes there is. I am adding the link in the related links area so you can find it easily.
Multiplication
You have to multiply to find area you have to add to find perimiter
by adding together the area of its parts
yes
You calcualte the area of a rectangle by multiplication as this finds the interior or area inside the rectangle. Calculating perimeter consists of adding the four lengths of the rectangle to find the border length.
adding, subtraction, multiplacation and divsion.
