Question

the diagonal of a field in the form of a quadrilateral are 106 m and 80 m and intersect each other at right angle find the cost of cultivating the field at the rate of 25.50rs per 100msq

pls help fast
thank you ​

Answer 1

Answer:

Step-by-step explanation:

As the Diagonals of a quadrilateral are bisecting each other at 90 degrees and making half each diognal on coalition. This means it is a parallelogram.

Also two congurent triangles are formed by the diogonals.

so now using formula 1/2 * B* H. We will find area of triangles which are form.

So area of each triangle is--

1/2 * 53* 40

=1060

so area of parallelogram= 1060*4=4240

Now finding the cost=>

4240/100*25.20 = rs. 1068.48
