A wooden path of length 19.8 m is completely covered with similar wooden planks, following the pattern shown below. The width of the path is 110 cm. Jo not write in this space 110 cm Wooden planks (a) What is the breadth of each wooden plank? (b) How many wooden planks were used to cover the entire path?

well what did you do it matters what you did : )

step-by-step explanation:

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.

3+3+3+2*2*2+29*12 = 365
