Question

a rectangular field is 50 M long and 30 M broad . find a perimeter b) the length of wire required to fence it thrice c)calculate area of a rectangular field​

Answer 1

Answer:  b) 160 c) 1500

Step-by-step explanation: b) 50 + 50 + 30 + 30 = 160 c) 50 x 30 = 1500

Answer 2

Step-by-step explanation:

$length \: of \: a \: field \: = 50m$

$breadth \: of \: a \: field \: = 30m$

$Perimeter \: of \: a \: field \: = ?$

We know,

Perimeter ( p ) = 2 ( l + b )

= 2 ( 50m + 30m )

= 2 × 80 m

= 160 m

The length of a wire required to fence it thrice

= 3 × 160 m

= 480 m

Area ( A ) = l × b

= 50 × 30 m

$= {1500m}^{2}$
