Question

find the cost of fencing a rectangular garden 400m long and 220m wide at the rate of Rs.50 per meter.​

Answer 1

Given:

Length of rectangular garden = 400m

Width (or) breath of garden = 220m

Cost per meter to fence = ₹50

To find:

Cost of fencing

Formula used:

$\boxed{\sf{Perimeter \:of \:rectangle = 2(Length+Breath)}}$

Solution:

${\sf{Perimeter = 2(Length+Breath)}}$

${\sf{\:\:\:\:\:\:\:\:\:\:\:\:\:\:=2(400+220)}}$

${\sf{\:\:\:\:\:\:\:\:\:\:\:\:\:\:=2(620)=1240m}}$

${\sf{Length\:of\:fencing=Perimeter \:of rectangle}}$

${\sf{Length\:of\:fencing=1240m}}$

${\bold{Cost\:of\:fencing=Length ×Cost \:per \:meter}}$

${\bold{\:\:\:\:\:\:\:\:\:\:\:\:\:\:=1240\cancel{m} × ₹50/\cancel{m}}}$

${\bold{\:\:\:\:\:\:\:\:\:\:\:\:\:\:= }}$$\bold{\red{₹62,000}}$

Answer 2

rupees 62,000

Step-by-step explanation:

perimeter of rectangle=2x(400+220)=1240m

cost of fencing=1240x50 =62,000
