A rectangle with length of 10 cm and width of 5 cm is split into 4 vertically. These were then split into half horizontally. Find the total perimeter of all the squares.
The answer is 80 cm.
Please explain working out.
so you have 8 squares, each (5/4) by (10/2). So their total perimeter is
8*2(5/4 + 10/2) = =100
Hmmm. It appears I have switched length and width. Make the change and you will get your answer.
