Question

Can any help me, with this question​

Answer 1

Given that,

l=20m

b=15m

d=4m (d-h)

We know that,

Area for coner its floor2d(l+b)+lb

=2(4)(20+15)+(20×15)

=8×35+300

=280+300

=580m

2

Rate of coner its floor Rs.12/m

2

∴ Total cost of coner its floor =580×12

Rs.6960

Then,

We get Rs.6960

hope it helps you

${\large{\pmb{\sf{\underline{\underline{Solution...}}}}}}$

$\quad{: \longmapsto{\sf{Area \: of \: a \: parallelogram = Base \times Altitude }}}$

• Substituting the values

$\quad{: \longmapsto{\sf{Area \: of \: a \: parallelogram = 10\times 3.5 }}}$

$\quad{: \longmapsto{\sf{Area \: of \: a \: parallelogram = 10\times \dfrac{35}{10} }}}$

$\quad{: \longmapsto{\sf{Area \: of \: a \: parallelogram = \cancel{10}\times \dfrac{35}{\cancel{10}}}}}$

$\quad{: \longmapsto{\sf{Area \: of \: a \: parallelogram =35 \: {cm}^{2} }}}$

$\quad\dag\underline{\boxed{\sf{Area \: of \: a \: parallelogram =35 \: {cm}^{2} }}}$

${\therefore{\underline{\underline{\sf{\red{The \: Area \: of \: Parallelogram is \: 35 \: {cm}^{2}}}}}}}$
