Answer 1

Answer:

x=20cm

Step-by-step explanation:

Before moving to question lets see what is perimeter.

"PERIMETER"

Perimeter is the sum of sides of the closed figure in which a given area is bounded.

IT can be calculated by some FUNDAMENTAL FORMULAES Or manually by adding the sides.

WHAT IS TRAPEZIUM.

Trapezium is the figure in which one opposite side is parallel and two other sides are joining to make it a polygon.

Now,

Lets understand the question in a very easy way by which you will surely understand how to solve such questions.

See,

Here a trapezium is given with the dimensions as,

x,x,x+10,x+2

Now,

As discussed above PERIMETER is the sum of sides bounded.

So,

sum of perimeter is=92cm.

And dimensions are

x,x,x+2,x+10

adding them and equalling to 92cm will give the value of x and we will be able to find out all the sided of trapezium.

HERE WE GO,

=>x+x+x+2+x+10=92cm

=>4x+12=92

=>4x=92-12

=>4x=80

=>x=80/4

=>x=20cm

NOW AS WE HAVE GOT THE VALUE OF "X"

So,we can easily find the values of other sides as:")

1st side=20cm

2nd side=x+2

=>20+2

2nd side=22cm

3rd side=x=20cm.

4th side=x+10

=>20+10

=>30cm.

These are the dimensions of Trapezium.

VERIFICation:-

sum of sides should be equal to":"

92cm.

=>20+20+22+30=92cm.

thus which is the required perimeter.
