Given : A rectangular garden is 79 m wide.
It costs 2244 to fence it at 6 per meter.
To Find : area of garden
(A) 8453 m²
(B) 8325 m²
(C) 8532 m²
(D) 8345 m²
Solution:
Let say Length of the garden is L m
Perimeter = 2 ( Length + Breadth )
= 2 ( L + 79) m
Cost of fencing per m is 6
Hence total cost of fencing = 6 x 2 ( L + 79)
= 12 ( L + 79)
12 ( L + 79) = 2244
=> L + 79 = 187
=> L = 108
Area = Length * breadth
= 108 x 79
= 8,532 m²
area of garden 8,532 m²
