Question

Find the area of the above quadrilateral ABCD​

Answer 1

Answer:

82.5 cm^2

Step-by-step explanation:

1/2 ( diagonal + sum of altitudes)

1/2 {75+(40+50)}

1/2 {75+90}

1/2 ×165

82.5 cm^2

Answer 2

given,

ABCD is a quadrilateral

In triangle ABC

area = 1/2 (b) (h)

=1/2 (75) (50)

= 1875 square metre

In triangle ACD

area = 1/2 (b) (h)

= 1/2 (75) (40)

= 1500 square metre

now,

area of quadrilateral ABCD = area of triangle ABC + area of triangle ACD

= 1875 + 1500

= 3375

hence, area of quadrilateral ABCD is 3375 square metre.
