Question

A rectangular hall 18 m long 16 m wide is
surrounded by a verandah 2 m wide. Find the area
of the Verandah.​

Answer 1

Step-by-step explanation:

Given that

Hall having length(l) is 18m

wide (w) is 16m

to calculate area of verandah

Solution

$area \: of \: verandah = total \: area - area \: of \: hall$

as here total area will be sum of area of verandah and area of hall.

as verandah is 2m in wide hence for total area length will be 20m and wide will be 18m.

hence

$total \: area = 20 \times 18 \\ = 360 {m}^{2}$

$area \: of \: hall = 18 \times 16 \\ = 288 {m}^{2}$

hence

$area \: of \: verandah = 360 - 288 \\ = 72 {m}^{2}$
