Given Question :-

A verandah of width 2.25m is constructed all along outside a room, which is 5.5m long and 4m wide. Find

1) The area of the verandah.

2) The cost of cementing the floor of the verandah at the rate of Rs 200 per m².

Answer

Dimensions of Room

Length of room = 5.5 m

Breadth of room = 4 m

$\rm :\implies\:Area_{(room)} = length \: \times \: breadth$

$\rm :\implies\:Area_{(room)}\: = \: 5.5 \times 4$

$\rm :\implies\:Area_{(room)} = 22 \: {m}^{2}$

Now,

Verandah of width 2.25 m is constructed all along outside the room,

so,

Outside Dimensions are as follow

Length of outside rectangle = 5.5 + 2.25 + 2.25 = 10 m

Breadth of outside rectangle = 4 + 2.25 + 2.25 = 8.5 m

$\rm :\implies\:Area_{(outside \: rect.)} = length \times breadth$

$\rm :\implies\:Area_{(outside \: rect.)} = 8.5 \times 10$

$\rm :\implies\:Area_{(outside \: rect.)} = 85 \: {m}^{2}$

Therefore,

$\boxed{ \pink{ \bf \: Area_{(verandah)}\: = \tt \: Area_{(outside \: rect.)} - Area_{(room)}}}$

$\rm :\implies\:Area_{(verandah)} = 85 - 22$

$\rm :\implies\:Area_{(verandah)} = 63 {m}^{2}$

Now,

$\rm :\implies\:Cost \: of \: cementing \: the \: floor \: 1 {m}^{2} = Rs \: 200$

$\rm :\implies\:Cost \: of \: cementing \: the \: floor \: 63 {m}^{2} = 200 \times 63$

$\therefore\rm\:Cost \: of \: cementing \: the \: floor \: 63 \: {m}^{2} = Rs \: 12600$
