Answer:

(i) 272.37 m²

Step-by-step explanation:

1) Split the diagram into two triangles- ABD and BCD

ΔABD:

Area of triangle = √s(s-a)(s-b)(s-c)

S = (a+b+c) ÷ 2

= (15+25+20) ÷ 2

= 30

Area = √30×(30-25)×(30-20)×(30-15)

= √22500

=  150 m²

ΔBCD:

S = (20+14+18) ÷ 2

= 26

Area = √26×(26-20)×(26-14)×(26-18)

= √14976

= 122.37 m²

Total Area = 150 + 122.37

= 272.37 m²

* Same calculation method for 2nd problem.
