I'll do the first one to get you started

# 4
a)

Area:

A=LW Start with the area of a rectangle formula


A=%281.5%29%280.25%29 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%2B2W Start with the perimeter of a rectangle formula


P=2%281.5%29%2B2%280.25%29 Plug in L=1.5 and W=0.25


P=3%2B2%280.25%29 Multiply 2 and 1.5 to get 3


P=3%2B0.5 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%261%2F6=25%2F6 and 2%261%2F3=7%2F3
