Work out the length of AB.
4vir4ik [10]
\frac{AB}{BC}   =   \frac{EB}{DC}

\frac{AB}{BC}   =   \frac{1.75 m}{7 m}

let AB = E

⇒                 (AB) (7 m) = (1.75 m) ( BC + AB)
                    (AB) (7 m) = (1.75 m) (1.5 m + AB)
                                      =  2.625 m²  +  (1.75 m ) (AB)
      (AB) (7 m - 1.75 m) = 2.625 m² 
                            ∴  AB =  2.625 m²  ÷  (5.25 m)
                           
<span>                   ⇒ the length of AB is 0.5 m</span>
