Question

if the area of trapezium square centimetre and length of the parallel sides are 8 cm and 12 CM respectively what is the distance between the parallel sides​

Answer 1

Answer:

This looks like a math homework question. I will solve your initial problem but using the sides 4, 8 and Area 30 instead.

Area formula for a trapezium (a.k.a trapezoid):

A=b1+b22h  

Where  A  is the total area,  b1  and  b2  are the parallell sides of the trapezoid, and  h  is the height of the trapezoid. And we want to know what? Right, the height, or  h . So, let’s rewrite the formula:

A=b1+b22h  

2A=(b1+b2)h  

2Ab1+b2=h  

Now let us look at what is known:

A=30  

b1=4  

b2=8  

Finally, insert the numbers:

2⋅304+8=6012=5  

Answer:  h=5
