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.
