Question

3. Length and breadth of a rectangular field are 22.5 m and 12.5 m respectively. Find:
(i) Area of the field
(ii) Length of the barbed wire required to fence the field

Answer 1

Given : l = 22.5 m b = 12.5 m

(i) area of field = 22.5×12.5 =281.25 m2

(ii) length of wire = perimeter of field

= 2(l +b)

=2(22.5+12.5)

=2×35

=70 m

Hope it helped u

Answer 2

area of of rectangular field= l*b
$22.5 \times 12.5 = 281.25$
(ii) length ofwire req=perimeter of field
2(l+b)
2(22.5+12.5)
2*35
70m
