Question

2 cross roads each of width 16 cm cut at right angles through the centre of a rectangular park of length 700 and breadth 300 m and parallel to its sides find the area of roads also find the area path excluding cross roads give the answer in hectars

Answer 1

Answer:1.5744 hectares,19.4256 hectares

Step-by-step explanation:

bro i think the 16 cm will actually be m,so i am takng the wigth of the crossroads as 16 m

so...

length = 700m

breadth = 300m

area of roads = sum of area of the two crossroads - intersection point

= 700 × 16  +  300 × 16  -  16 × 16  

= 11200 + 4800 - 256

= 15744 m²

= 1.5744 hectares

area of the whole field = 700×300

= 210000 m²

so area without crossroads = 194256 m² = 19.4256 hectares

hope it helped you out!!
