Divide 15000 by 50 to get the square meters (area of the field), then

divide the area by the length & that is the width. Then add twice the  
length plus twice the width to get the perimeter & multiply that by 3.  
 
Q3 Assuming you have to cut the bricks & you have no wasted bricks, then  
find the area of each brick by multiplying the width by the length of the  
bricks. Then get the area of the lane by multiplying the length times the  
width of the lane. Divide the area of the lane by the area of one brick to  
get the number of bricks.

1. area = 903 = 32m 25cm * breadth = 32.25 * breadth

breadth = 903 / 32.25 = 28m

area = 250 * breadth  
 
breadth = 30000 / 250 = 120m  
 
perimeter = 2 ( 120 + 250 ) = 740  
 
distance travelled by boy = 3 * 740 = 2220 m  
 
3. area of lane = 240 * 12 = 2880 sq m  
 
area of brick = 22.5 * 10 = 225 sq cm = 2.25 sq m  
 
number of bricks = area of lane / area of brick = 2880 / 2.25 = 1280
