Question

plz help guys .....vry much imp.

Answer 1

given,
length=58m
breadth=45m
we know that,
perimeter of a field
=2(l+b)
=2x(58+45)m
=206 m
hope it's the required answer

Here is your answer
Length of rectangle = 58 m
Breadth of rectangle = 45 m

After excluding square corner of side 8 m

Length = 58 - 8 -8 = 42 m
Breadth = 45 - 8 - 8 = 29 m

Now
Perimeter = 2(L + B)
$= 2(42 + 29) \\ = 2(71) \\ = 142 \: m$

Hence Perimeter of figure excluding squares is 142m
