Question

Find the value of W if A=LW, A=8m^2, and L=4m

PLEASE HELP

Answer 1

`A=8 \ m^2, \ \ L=4 \ m \\\\ A=LW\\\\8 \ [m^2]= 4 \ [m ]\cdot W \ \ / :(4 \ [m]) \\ \\W=(8 )/(4) \cdot ([m^(2)])/([m])= 2 \ m \\ \\\\Answer : \ W =2 \ m`

Answer 2

`A=LW\ \ \ \ |divide\ both\ sides\ by\ L\\\\W=(A)/(L)\\===============\\\\A=8m^2;\ L=4m\\\\W=(8m^2)/(4m)=2m^(2-1)=2m`


A=lW divide both sides by L

W=A / L
----------------------------------------------------------------------
A=8m^2; L=4m

W=(8m^2) / (4m) = 8 / 4 * m^2 / m =2m
