Pythagoras theorem should be used after which area would be found out by heron's formula or we need to simply multiply it the height and base with each other ?... help please help...

Now i will find area of all

1) - 1/2×5×6 = 15

2) - 1/2(6+5)*12=66

3) - 1/2*15*10=75

4) - 1/2*7*7=24.5

5) - 7*7=49

6) - 1/2*7*13=45.5

Now add all the products

15+66+75+24.5+49+45.5=275m²

∴ Area of the plot is 275m²
