AREA FOR EACH PART

AREA FOR PART 2 :



Formula for area trapezium = ½ ( a + b ) h
= ½ ( 8 + 6 ) 1
= 7cm²

AREA FOR PART 3 :



Formula for rectangle = length x width
= 8 x 2.5
=20cm²



AREA FOR PART 4 :

Formula for trapezium = ½ ( a + b ) h
= ½ (7 + 8) 0.6
= 4.5cm²

AREA FOR PART 5 :


Formula for rectangle = length x width
= 7 x 6
= 42cm²

AREA FOR PART 6 :


Formula for trapezium = ½ (a+b) h
= ½ (7+8) 0.6
= 4.5cm²

AREA FOR PART 7 :


Formula for rectangle = length x width
= 8 x 2.4
= 19.2cm²

AREA FOR PART 8 :



Formula for trapezium = ½ (a+b) h
= ½ (6+8) 1
= 7cm²

TOTAL AREA OF THE MODEL :
Area :
= Part 2 + Part 3 + Part 4 + Part 5 + Part 6 +Part 7 + Part 8
= 7cm² + 20cm² + 4.5cm² + 42cm² + 4.5cm² + 19.2cm² + 7cm²
= 104.2cm²
