Find the area of the following figure. solve and show your solution

help pls!

Step-by-step 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

sites:

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
