Step-by-step explanation:
Left side: 18cm
Under that: 5cm
5cm again
Perimeter = 76
Because: 20 + 18 + 18 + 5 +5 +5 +5 = 76
Find a number that you can make 10,100,or any 1 followed by zeroes
then,multiply both numerator and deno with that number
Then write down just the top number, putting the decimal point in the correct spot (one space
from the right hand side for every zero in the bottom number)
