Question

A rectangular garden is (2x+5) meters long and (x- 1) meters wide. It is surrounded by 3m path walk. At least how many meters of wire should be bought to enclose the garden with the path walk?

Answer 1

Answer:

Length of garden =48 m

Breadth of garden =32 m

Perimeter =2(48+32)m=160 m

∴ Length of fencing used to enclose the garden =160 m

Cost of fencing 1 m=Rs.98

∴ Cost of fencing 160 m=Rs.(98×160)=Rs.15680

So, total cost =Rs.15680
