Answer:
Explanation:
1)sol;
perpendicular=15cm
base=25
now,
area of right angled triangle=1/2 p*b
=1/2*15*25
=187.5cm^2
2)sol;
length=12cm
now,
area of square=l^2
=(12)^2
=144cm^2
3)sol;
radius=20cm
now,
area of circle=
r^2
=
*(20)^2
1257.14cm^2
5)sol;
length=9cm
now,
area of square=l^2
=(9)^2
=81cm^2
