Answer:
132 ft²
Step-by-step explanation:
The shape is composed of a rectangle and a triangle.
Area of the shape = area of rectangle + area of triangle
Area of rectangle = L*W
L = 12 ft
W = 8 ft
Area of rectangle = 12*8 = 96 ft²
Area of triangle = ½bh
b = 8 ft
h = 21 - 12 = 9 ft
Area of triangle = ½(8*9) = 36 ft²
Area of the shape = 96 + 36 = 132 ft²
We have the equation:
4x - 3 = 2x + 5
Let's to change "-3" to the right side of equation, but changing the sinal
4x = 2x + 5 + 3
4x = 2x + 8
Now, we let's to change "2x" to the left side of equation. But, we also will go to change the sinal
4x - 2x = 8
2x = 8
We pass "2" dividing by the 8
x = 8 ÷ 2
x = 4
Tha answer to this questions is ,
X = 4
I hope this has helped.
