Step 2:
How many steps will be required to fully open the bleacher to reach its maximum floor clearance?
[tex]\begin{gathered} Since\text{ AC =40 cm , and Length of floor clearance = 2. 8 m \lparen 2800 cm \rparen} \\ Then\text{ the number of steps =}\frac{2800\text{ cm}}{40\text{ cm}}=\text{ 70 steps} \end{gathered}[/tex]CONCLUSION:
There are 70 steps that will be required to fully open the bleacher to reach its maximum floor clearance.
