Question

A picture is painted on a cardboard ICM long and 5 cm wide such that there is a margin of 1.5cm along each of its side . Find the total area of margin ?

ans - length of painting = 5cm
breath of painting = 8cm

length with margin = 5+1.5+1.5
= 35 m
breath with margin = 8+1.5+1.5
= 38 m
area of margin = area of abcd.- abcd
length × breath - length × breath
35× 38 - 5× 8
1330- 40
1290 m
area of abcd = length × breath
= 5 × 8
= 40m
​

Answer 1

Answer:

length of painting = 5cm

breath of painting = 8cm

length with margin = 5+1.5+1.5

= 35 m

breath with margin = 8+1.5+1.5

= 38 m

area of margin = area of abcd.- abcd

length × breath - length × breath

35× 38 - 5× 8

1330- 40

1290 m

area of abcd = length × breath

= 5 × 8

= 40m
