Answer 1

Answer:

Question:-

The length of a rectangular garden is twice its breadth. If the length of the garden is 90 m, then how much will it take to fence with a wire net, costing Rs 15 per metre.

Solution:-

Length = 2 × breadth

90 = 2 × breadth

$\frac{90}{2}$ = breadth

45 = breadth

$Perimeter = 2(l + b)$

$= 2(90 + 45)$

$= 2*135$

$= 270$ $m$

Cost of fencing = Rs 15 per metre

Total cost = $Perimeter * cost$ $Per$ $Metre$

$= 270 * 15$

$= 4050$

It will take Rs 4050 to fence the garden.
