A painting is painted on a cardboard 19 cm and 14 cm wide,such that there is a margin of 1.5 cm along each of its sides. Find the total area of the margin?​

Answer 1

Step-by-step explanation:

length of cardboard = 19 cm

breath of cardboard =14 cm

Area of cardboard =(19×14)cm×cm

=266cm×cm

Given:-

margin=1.5cm

new length =19- (1.5×2)

= 19 - 3

= 16 cm

new breath = 14 - (1.5×2)

= 14 - 3

= 11 cm

area of cardboard except margin

= (16×11)cm×cm

= 176 cm×cm

area of margin = (266-176 )cm×cm

= 90 cm ×cm
