Question

plz very important answer this question​

Answer 1

Answer:

570 sqm.

Step-by-step explanation:

∆BAD is a right angled triangle,

thus, area of right angled triangle= 1/2×base×height

= 1/2 × 9 × 40

= 1/2×360

= 180 sqm.

In ∆BCD

area of triangle= 1/2×base×height

= 1/2 × 60 × 13

= 1/2×780

= 390 sqm.

thus, area of quadrilateral ABCD = area of ∆BAD + area of ∆BDC

= 180 + 390

= 570 sqm.

Thus, the are of quadrilateral ABCD is 570 sqm.
