Hello,

$(x+7)(x+2)=50\\\Rightarrow\ x^2+9x+14=50\\\Rightarrow\ x^2+9x-36=0\\\Rightarrow\ x^2+12x-3x-36=0\\\Rightarrow\ x(x+12)-3(x+12)=0\\\Rightarrow\ (x+12)(x-3)=0\\\Rightarrow\ x=-12\ or\ x=3\\If \ x=-12\ then\ x+7$

1 metre = 100cm
2 metres = 200cm

200 / 80 = 2.5

2 boards is the answer. Please make this answer the brainiest.
