We trying out lots of new things in math for the new year. Last week we worked on negative numbers and this week we are learning formulas for perimeter and area for squares and rectangles!
perimeter = the distance around around a figure
a square has four congruent(equal) sides SO the perimeter can be found with this formula
P = 4s (perimeter = 4 times the measure of one side)
a rectangle has two pair of congruent sides SO the perimeter can be found with this formula
P= 2l + 2W ( perimeter = 2 times the length + 2 times the width)
Area is the measure of the space inside of a figure.
the area of a square or a rectangle can be found with this formula
A = l x w ( area = length times width)
