Question

Area of a rectangular field is 21/2 m?. the length of the
field is 10 p/4 m,
find the breath​

Answer 1

area of rectangle = l * b

b = area/length

b = 768/32

b = 24cm

perimeter of the field = 2( l + b )

= 2 ( 32 + 24)

= 2 * 56

= 112cm

the cost of fencing the field = 112 * 20

= rs 2240

u can do like that

Answer 2

Step-by-step explanation:

Let the breadth to be b

area of rectangle = l x b

According to the question:

10/4 x b = 21/2

10b = 21/2 x 4

10b = 42

b = 4.2m

breadth = 4.2meter
