Question

Q1: The length of a rectangular mat is 10cm and its breadth is 20 cm.
a) Find its area and perimeter
b) Find the cost of embroidering it at Rs 5 per cm2
c) Find the cost of bordering it at Rs 3.50 per cm.

Answer 1

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.
