Question

Find the diagonal of a quadrilateral whose area is 20 square cm and the two altitudes are 1cm and 1.5cm​

Answer 1

Step-by-step explanation:

Given that, the area of a quadrilateral = 20 cm2 We know that, the area of a quadrilateral = (1/2) (diagonal) (sum of the altitudes) 20 = (1/2) (1+1.5) BD 20 = (1/2) (2.5) BD 20×2 = 2.5 BD 40 = 2.5 BD BD = 16.
