Question

If the area of a rectangular plot is 144 sq. m and its length is 16 m. Find the breadth of the plot and the cost of fencing it at the rate of 76 per metre. .​

Answer 1

Answer:

Breadth = area \ length

B = 144/16

= 9

cost of fencing 76 per metre. .

= 9x 76

= 684

Answer 2

Answer:

area of rectangle = l × b

144 m^2 = 16 × b

144/16 = b

9 = b

p of rectangle = 2{l +b}

p of rectangle = 2{16+9}

= 2{25}

p of rectangle = 50

rate of fencing per m. = 76

rate of fencing 50 m. = 76 ×50

ans. = rs. 3800
