Since, you have not included the formula, I will work here with the formula for constant accelaration motion that relates the four variables: displacement (d), Vo (initial velocity), a (acceleration) and t (time).
1) displacement formula:
2) Subtract the term Vot from both sides:
3) Multiply both sides by 2:
4) Divide both sides by t²
So, you have obtainded:
a = 2[d - Vo×t] / t²
Yet, you can arrange it in different ways. For example, you might separate into two terms:
<span> Add x to both lenght and width and you get 25+x and 10+x. Set up equation with new area </span> <span>(25+X)(10+X)=1000 </span> <span>solve using quadratic formula
