Step-by-step explanation:
quadrilateral having one diagonal is 40m .
divides the field into two trianglular parts.
The length of the heights to the diagonal is 12 m and 14 m respectively
area of the triangle is =1/2×base×height
area of quadrilateral is = area of one triangle+area of second triangle
= 1/2(40×12)+1/2(40×14)
=1/2(480+560)
=1/2(1040)m2
=520m2
fence the field at the rate of 15 per m2
1 m2 -->. 15 rupee
520 m2--> 15×520 rupe
= 7800 rupee
