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

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
