1. A rectangular field is 100 m long and 52.5 m broad. It has to be fenced to keep the cattle away. A) How much wire is needed for fencing? b) How much space is there for him to plough the field for cultivation?

See the answers below

Step-by-step explanation:

Given data

Dimension of the field

Length = 100m

Width= 52.5m

A). Perimeter fencing= 2L+2W

P= 2*100+ 2*52.5

P= 100+  105

P = 205m

B. Area= L*W

A= 100*52.5

A= 5250m^2

2? if not the correct answer you might need to provide more information

step-by-step explanation:

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
