Answer:
the sum of parallel sides will be 26 cm
Step-by-step explanation:
A= 1/2(a+b)*h
130= 1/2(a+b)*10
130*2= (a+b)*10
260= (a+b)*10
260/10= (a+b)
26= a+b
hence, sum of parallel sides is 26 cm

Answer:
Here,
Area of the trapezium = 130 cm²
Altitude/height= 10 cm
Let The parallel sides be a and b
Since we know the formula for the area of a trapezium is ½×h× [a+b]
Therefore according to the question,
½×h× [a+b]=130 cm²
=>½×10×[a+b]= 130
=>a+b= 130/5 = 26 cm
[cancelling 2 and 10 to get 5 and dividing 130 by that 5]
