Question

the area of rectangular garden is 77/2 find the length of the garden if its breadth is 49/12 m also find the cost of fencing the garden atrupees 63/5 per metre​

Answer 1

Answer:

Lenght = 66/7

Cost = 340.50 rupees

Step-by-step explanation:

Area = 77/2

Breadth = 49/12

Length = y

y × 49/12 = 77/2

49y/12 = 77/2

49y = 77/2 × 12

y = (77 × 6) / 49

y = (11 × 6) / 7

y = 66/7

Hence, lenght = 66/7 m

Perimeter = 2 ( l + b )

2 (66/7 + 49/12)

2 ( 792/84 + 343/84)

2 (1135/84)

1135/42

Cost = 63/5 per meter

1135/42 × 63/5

227/14 × 21

227/2 × 3

681/2

340.5

Hence Cost = 340.50 rupees
