Answer:
a) 30 cm
b) 20 cm
Step-by-step explanation:
Rectangle B's perimeter is 10+10+5+5 which is 30
Square C's perimeter is 5+5+5+5 which is 20
Let’s set this equation up to make this easier.
melanie= 2 1/5 miles walked
cathy= 1 3/4 more times than melanie.
when an equation says the word, more than this means adding. when it says less than this means subtraction. when it says times (in this question) then multiply.
so, if cathy walked 1 3/4 more times than melanie what we would do is multiply 1 3/4 to what melanie was walking. so 2 1/5 times 1 3/4 which equals 3.85.
so overall, cathy walked 3.85 more miles than melanie.
