Question

A diagonal of a quadrilateral is 12m. the off and 5m what is the area of the quadrilateral ? Options:- a) 54sq.m b) 108 sq.m c) 54m d) 108 m​

Answer 1

A quadrilateral can be split into 2 triangles

Diagonal is 12m and one side is 5m

So area of first triangle is 1/2 x 12 x 5 = 30

Area of other triangle is also 1/2 x 12 x 5 = 30

Total area = 30 + 30 = 60 (Approx)

Since 54 is closer to 60, The correct answer is (a) 54 sq.m (Since the area was an approximate)
