Let the length be L
Let the width be W
L=2W
2(L+W)=24
2(2W+W)=24
2 X 3W=24
6W=24
W=4
L=8
Area = L *W
Area = 4*8=32
Hello there!
In order to solve that equation, you would need to distribute the 3 inside the parenthesis.
-10x + 3(4x - 2) = 6
-10x + 12x - 6 = 6
Then you would need to keep the variable in the left and everything else to the right - in other words, solving for x.
-10x + 12x - 6 = 6
2x = 12
x = 6
Your answer would be 6.
Area of the blue = Area of the rectangle - Area of the triangle
Area of rectangle : Length x Width
so, 20 x 10= 200
Area of triangle: 1/2 x base x height
so, 1/2(10 x 8) = 40
So area of the blue is 200-40 which is equal to 160
