Answer 1

Hey dear!!


Here is yr answer......


1.

Given,

l = 12 1/2 = 25/2 cm

b = 10 2/3 = 32/3 cm


(i) perimeter

perimeter of recrangle = 2(l+b)

= 2(25/2+32/3)

= 2(75+64/6)

= 2(139/6)

= 139/3

= 46 1/3


Therefore, perimeter of rectangular sheet = 46 1/3 cm


(ii) area

area of rectangle = l×b

= 25/2 × 32/3

= 400/3

= 133 1/3


Therefore, area of rectangular sheet = 133 1/3 cm²



2. Given,

In an orchard 1/5 are orange trees

3/13 are mango trees

no. of banana trees = 148


Now,

let the no. of trees in the orchard = x

1/5x are oragne trees

3/13x are mango trees


remaining trees = 1-(1/5+3/13)

= 1-(13+15/65)

= 1-28/65

= 65-28/65

= 37/65

= 37/65x


37/65x = 148

x = 148 × 65/37

x = 260



No. of orange trees = 1/5x

= 1/5 × 260

= 52


No. of mango trees = 3/13x

= 3/13 × 260

= 60


No. of banana trees = 148


Total no. of trees = 260


Hope it hlpz....
