Answer:

$\large\boxed{h=\dfrac{2A}{b_1+b_2}}$

Step-by-step explanation:

$A=\dfrac{1}{2}h(b_1+b_2)\qquad\text{multiply both sides by 2}\\\\2A=2\!\!\!\!\diagup\cdot\dfrac{1}{2\!\!\!\!\diagup}h(b_1+b_2)\\\\2A=h(b_1+b_2)\qquad\text{divide both sides by}\ (b_1+b_2)\\\\\dfrac{2A}{(b_1+b_2)}=\dfrac{h(b_1+b_2)}{(b_1+b_2)}\qquad\text{cancel}\ (b_1+b_2)\\\\\dfrac{2A}{b_1+b_2}=h\to h=\dfrac{2A}{b_1+b_2}$

Ann made a 33-step staircase using 1818 toothpicks as shown in the figure. How many toothpicks does she need to add to complete

malfutka [58]

You would take 1818÷33=55.09

55.09 is how many toothpicks it took for each step made

Then you would take 55.09×55=3029.95

You can make sure this is correct by taking 55.09×33=1817.97 which would actually be 1818 because you had to round it up
