Question

* Find the length of diagonal AC in the adjoining figure if the
area of quadrilateral ABCD is 35 cm². please help me in this question ​

Answer 1

Step-by-step explanation:

here... the sum of the areas of the four triangles is equal to the area of the quadrilateral (35 cm square) ...so we can use this relation to get to the answer. Also in each of the four triangles atleast one angle is 90° .Hence all the four triangles are right angled triangle .So we can use the formula (1/2 ) x base x height as the area of all four triangles...That is what i have done in the attached photo as u can see .
