Please help me with my question!!

Answer 1

3247.50 cm sq

Explanation:

Answer 2

Explanation:

Area of triangle = (1/2)bh

`=(1)/(2)*25*21.65\\\\`

= 270.625 cm²

Area of 6 triangles = 6 * 270.625

= 1623.75 cm²

Trapezium:

a = 25 cm

b = 25 + 12.5 +12.5 = 50 cm

h = 21.65 cm

`Area=((a+b)*h)/(2)\\\\=((25+50)*21.65)/(2)\\\\=(75*21.65)/(2)`

=811.875 cm²

Area of two trapezium = 2 *811.875

= 1623.75 cm²

Area of star = 1623.75 +1623.75

= 3247.50 cm²
