Question

1.a rectangular sheet of paper is 12 1/2 cm long and 10 2/3 cm wide.find its

(i) perimeter
(ii) area

2.In an orchard, 1/5 are orange trees, 3/13 are mango trees and the rest are banana trees. if the banana trees are 148 in number, find the total number of trees in the Orchard

Answer 1

Heya


1.) Length = 12 1/2 = 25/2 cm

2.) Breadth = 10 2/3 = 32/3 cm


Perimeter = 2(L+B)

=2( 25/2+32/3)

= 2 (25*3/2*3+32*2/3*2)

= 2 (75/6 + 64/6

= 2 * 139/12

= 278/12

Perimeter = 278/12



ii) Area of rectangle = L*B

= 25/2*32/3

= 25*32/2*3

= 800/6

= 133 1/3

= 23 1/6


Area = 23 1/6


2) Orange trees =1/5

Mango trees = 3/13

Banana trees = 148


Total trees = 1/5 + 3/13 + 148/1

= 1*13 + 3*5 + 148*65/65

= 13+15+9,620/65

= 9648/65

= 148 28/65


Total no. Of trees = 148 28/65




Hope it helps you ^_^
