Question

a flied in the shape of a Trapezium has parallel sides as 23 metre and 11 metre while the non parallel sides are 14 and 15 metre find the amount of money farmer has to pay if the cost of sowing the seeds square per m^2 is is Rs 132

Answer 1

Answer:

Here is your answer

Step-by-step explanation:

So Area of Trapezium= Area of Rectangle + Area of Triangle

 

Use Heroins Formula to find Area of Triangle with sides 13, 14, 15

 

s equals fraction numerator 13 plus 14 plus 15 over denominator 2 end fraction equals 21 square root of 21 cross times 8 cross times 7 cross times 6 end root equals 7 cross times 3 cross times 4 equals 84 space s q. space m  A r e a space o f space T r i a n g l e space w i t h space b a s e space 15 space i s space g i v e n space b y 1 half cross times 15 cross times h e i g h t equals 84 h e i g h t equals 56 over 5 m  A r e a space o f space R e c tan g l e equals 56 over 5 cross times 10 equals 112 space s q. m  S o space a r e a space o f space t r a p e z i u m equals 84 plus 112 equals 196 space s q. space m
