Answer:

(i)for the first one there are 3 triangles and 1 trapezium

the area formula of traingle is = 1/2× BH

area of trapezium = a+b×h the whole divided by two

1 at traingle = 1/2× 6×2

= 6cm

2nd triangle= 1/2×10× ( 2+5)

= 35cm

trapezium = 6+(5+2)×6

________

2

= 39cm

now add the areas of three triangles and one trapezium

6+35+39=80sq.cm

( ii ) in this There are 2 rectangles and triangles

area formula of rectangle is l×b and triangle is 1/2×bh

1st rectangle = 60×30

= 1800 cm

2nd rectangle =60×25

= 1500 cm

you can see a line indicates 80 cm we know one side of rectangle is 60 cm so 80 - 60 = 20

the double line in both the triangles indicate they are equal so 20/2 = 10 cm

so base of both the traingles is 10cm

area of both the triangles is =2× ( 1/2 ×10×25 )

( since two triangles area we multiply with 2 at initial )

= 2×125

250 cm

now add all the areas of both the rectangles and triangles

= 1800+1500+250

=3550 sq.cm

hope this could help u , if so please mark me as brainalist
