the area of the rectangular Garden of length 40 m is 1000 square metre find the breadth of the garden and its perimeter is to be enclosed by 3 rounds of living an entrance of 4 m. find the cost of fencing the garden 250 rupees per metre
Answers
Answer:
Breadth = 25 m
Cost of fencing = Rs 94500
Step-by-step explanation:
Area of a rectangle = Length x Breadth
In the given question, area of rectangular garden = 1000 sq. m
Length = 40 m
Breadth = Area/ length = 1000/40 = 25 m
Now, Perimeter of rectangular garden
= Length + Breadth + Length + Breadth
= 2 ( length + breadth)
= 2 ( 40 + 25)
= 130 m
However, 4 m of entrance is to be left open. Hence length of total boundary to be fenced = 130 - 4 m = 126 m
Further, it has to be fenced 3 times. Hence total length = 126 x 3 = 378 m
Cost of fencing 1 m = Rs 250
cost of fencing 378 m = Rs 250 x 378 = Rs 94500
Answer:
Step-by-step explanation:
Area of Garden = 1000 Sq. m
Area = Length* width;
1000 = 40 * W;
W = 25;
Perimeter of Garden = 2 (L+W); (Where the fencing to be done);
Total Perimeter = 2 (40 + 25) = 2*65 = 130 m;
Entrance of the garden = 4 m; (Where fencing is not required)
Total length where the fencing has to be done = 130 - 4 = 126 m:
total 3 round of fencing;
Total total length = 3*126 = 378 m;
Per meter cost of fencing is rupees 250;
Total cost = 378 * 250 = 94500 rupees
