Question

Find the area of a rectangular plot, one side of which measure $35m$ and the diagonal is $37m$.

Answer 1

Given that:

Length $l=35m$, Diagonal $d=37m$

Breadth $b=?$, Area $A=?$

$b^2=d^2-l^2$

$b^2={37}^2-{35}^2$

$b^2=1369-1225$

$b^2=144$

Breadth $b=12m$

Now,

Area $A=l\times b$

$A=35\times 12$

$A=420m^2.$
