Question

Find the value of W if A=LW,
A=16m^2
L=8m

W=?

Answer 1

so if A=LW
and A=16m^2
and L=8m
A=LW
16m^2=8m(W)
divide both sides by 8m
2m=W

or you could convert the equation A=LW to A/L=W to solve for W
so A/L=W or (16m^2)/8m=W
cancel out one 'm' (16m)/8=W
simplify the fraction 2m/1=W
2m=W

Answer 2

`A=LW \\A=16m^2 \\\\ 16m^2=8m*W \\\\ W=16m^2:8m \\\\ \boxed{W=2m}`
