Question

11. Find the cost of watering a trapezoidal field whose parallel sides are 10 m and 25 m respectively, the
perpendicular distance between them is 15 cm and the rate of watering is 4
per
m.
12. The parallel sides of a trapezium are 25 cm​

Answer 1

Explanation:

Considering the distance between parallel sides (h) = 15 M

Let one parallel side of the trapezoid be `a` = 10m

Another parallel side be `b` = 25m

The height that is the distance between the parallel sides = 15m

Area = [(a+b)/2]h

= [(10+25)/2 × 15] m²

= [35/2 × 15] m²

= [17.5 × 15]m²

= 262.5 m²

Cost of watering one m² area = Rs 4

Cost of watering 262.5 m² area = Rs 1050 please mark me as brainlist
