Question

find area of the following polygon

Answer 1

A)

Area of triangle = 1/2 x base x height

Area of triangle = 1/2 x 8 x 10 =40 cm²

B)

Area of trapezium = 1/2 (a + b) x h

Area of trapezium = 1/2 (10 + 22) x 20 = 320 cm²

C)

Area of triangle = 1/2 x base x height

Area of triangle = 1/2 x 22 x 16 = 176 cm²

d)

Area of triangle = 1/2 x base x height

Area of triangle = 1/2 x 18 x 24 = 336 cm²

e)

Area of trapezium = 1/2 (a + b) x h

Area of trapezium = 1/2 (24 + 16) x 18 = 360 cm²

f)

Area of triangle = 1/2 x base x height

Area of triangle = 1/2 x 8 x 16 = 64 cm²

Total area = 40 + 320 + 176 + 336 + 360 + 64 = 1296 cm²
