Answer 1

Answer:

161m

Explanation:

we have given outer

lengeth = 43 m

bredth = 27 m

now inner length and bredth

inner length

$= 43 - 1.5 - 1.5$

$43 - 3 = 40 \: m$

inner bredth

$27 - 1 - 1$

$27 - 2 = 25$

now area of shaded region = area of outer rectangle - area of inner rectangle

then area of outer rectangle = l ×b

= 43 × 27

= 1161 m

and area of inner rectangle = l' × b'

= 25×40

= 1000 m

area of shaded region = 1161 -1000

161m

hope it help
