Answer:

35/42 = b/7    and b= 35/6

Step-by-step explanation:

Our base is unkhown so it will be the variable in our equation :

  • Let A be the area , h the height and b the base
  • A = b*h
  • 35/42 = b/7  this is the equation , let's solve it
  • (35*7)/42 = b
  • (35*7)/ 7*6 =b
  • 35/6 = b

so b is 35/6 cm
