What is the value of g? 25(g−7)=3 enter your answer in the box

First open the bracket by multiplying with 25

25g -25×7 =3

25g -175 =3

Add 175 to both sides

25g -175+175= 3+175

25g = 178

g = 178/25 is the value.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
