Question

A carpet is 5 m long and 4 m wide. Find its price at the rate of $ 205 per square meter

Answer 1

Given

$\bold{Length \ of \ the \ carpet} = 5 \ m\\\bold{Breadth \ of \ the \ carpet} = 4 \ m$

SOMETHING YOU NEED TO KNOW

Area of a rectangle = Length * Breadth

Perimeter of a rectangle = 2(Length + Breadth)

$\implies 4 * 5\\\implies 20 \ m^{2}$

Cost per square meter = 205 $

$\implies \bold{Cost \ for \ 20 \ meters} = 20 * 205$

                                         $= \boxed{\boxed{\bold{4100 }}}}$

                                                     

Answer 2

Answer:

area of rectangle =L*B

perimeter of a rectangle =2(l+b)

=2(5+4)

=2*9

=18

cost of per meter is $205

cost of 18m =205*18
