Find the area of these shapes, i’ve tried them but i’m not sure if they’re correct

a)

A = 5m × 7m = 35 m²

b)

A = 4cm×8cm/2 = 4cm×4cm = 16 cm²

c)

A = 1,2km×0,8km/2 = 0,96km²/2 = 0,48 km²

d)

A = (8m + 10m)·3m/2 = 18m·3m/2 = 9m·3m = 27 m²

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
