A scale drawing of Jacks living room is shown below. If each 2cm on the scale drawing equals 10 feet, what are the actual dimensions of the room. 4cm by 6cm

Hope dis helps :> Have a great day

Step-by-step explanation:

Drawing : Actual

Scale

           2 : 10

     2 cm : 10 feet

Length

    6 cm : 30 feet

Width

    4 cm : 20 feet

The actual dimensions of the room are - Length=30 feet, Width=20 feet.

The answer is the second one.

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

ok then what happened.
