Question 182904
I'll do the first one to get you started


# 4

a)


Area:


{{{A=LW}}} Start with the area of a rectangle formula



{{{A=(1.5)(0.25)}}} Plug in {{{L=1.5}}} and {{{W=0.25}}}



{{{A=0.375}}} Multiply 1.5 and 0.25 to get 0.375



So the area is 0.375 square meters


-------------------------------


Perimeter: 


{{{P=2L+2W}}} Start with the perimeter of a rectangle formula



{{{P=2(1.5)+2(0.25)}}} Plug in {{{L=1.5}}} and {{{W=0.25}}}



{{{P=3+2(0.25)}}} Multiply 2 and 1.5 to get 3



{{{P=3+0.5}}} Multiply 2 and 0.25 to get 0.5



{{{P=3.5}}} Add



So the perimeter is 3.5 meters



================================================


b)


Use the same area and perimeter formulas to solve this part.


Note: you need to convert the mixed fractions to improper fractions first. So {{{4&1/6=25/6}}} and {{{2&1/3=7/3}}}
