Answer:
Area of the Trapezoid is= 
Step-by-step explanation:
The given figure is in the shape of a trapezoid:
Area of a trapezoid= (1/2)*(Sum of parallel opposite sides)* (Distance between the parallel sides)
The parallel sides are: 6 cm and 3 cm
Distance between parallel sides= 3 cm
Area:

Area of the Trapezoid is= 
Answer:

Step-by-step explanation:
We require 2 equations with the repeating decimal after the decimal point in both equations.
The bar above 136 indicates that 136 is being repeated
let x = 0.136136...... → (1) Multiply both sides by 1000
1000x = 136.136.... → (2)
Subtract (1) from (2) to eliminate the decimal part
999x = 136 ( divide both sides by 999 )
x =
