Given , length of room ( l ) = 13 m

breadth of room = 9 m

_______________________________
step 1 Find area of the room :
_______________________________

area of room = length × breadth

= 13 × 9 = 117 m^2

_______________________________
let the length of carpet be ' x m '

Given ,breadth of carpet = 75 cm

= 75 /100 = 0.75 m

_______________________________
step2 Find area of carpet :
_______________________________

area of carpet = length × breadth

= x × 0.75 m^2

_______________________________
step3 Find length of required carpet :

area of carpet = area of room

x × 0.75 = 117 m^2

x = 156 m = length of required carpet

cost of carpeting 1 m = Rs 50

cost of carpeting 156 m = 156 × 50

= Rs 7800

therefore , cost of carpeting = Rs 7800
