Question

the base of a parallelogram shaped field is twice its altitude. the cost of flying grass in the field at Rupees 1500 per hectare is rupees 12000. find the area and base of the field. also find the fencing required to fence the field once if its other adjacent side is 150m. ​

Answer 2

Answer:

let altitude of the parallelogram=X meters

so,base=2x meters

Area of the field= (2x × x) m s.q.

rate of lying grass in the field= 1,500 per hectare

total cost lying grass in the field = 12000

area of field= 12500/1500hectares

= 8 hectares

= 80000m s.q. (1ha= 100×100m s.q.)

now,2x s.q. = 80000

so,x s.q. = 80000/2

x s.q. = 40000

x = √40000

x = 200m

base of the parallelogram= 2×200m

=400m

the other side= 150m

perimeter of parallelogram= 2(length+breadth)

2×550

1100m
