Step-by-step explanation:
Given that
Length-10cm
Breadth-20cm
(a)Hence,area of rectangle-l×b
putting the given value,weget- 10×20-200cm2.
And perimeter of a rectangle-2(l+b)
hence..2(10+20)=2(30)
=60cm
(b)cost of embroidering per cm2is Rs5
Hence ,cost of embroidering of 200cm2 is-200×5-
Rs 1000
(c)cost of bordering per cm is Rs
3.5,hence cost of bordering of 60cm is=60×3.5=Rs210.
