Question

What is the value of x?

3
4
6
8

Answer 1

x=4 that is Option 2 is correct.

Explanation:

The given figure is rectangle and since the opposite sides of rectangle are equal

hence, 18=10+2x

After simplification so as to get the value of x we get:

18-10 =2x

8=2x

After further simplification we get:

x=4

Therefore, option 2 is correct.

Answer 2

The longer sides of the rectangles should be the same value, so we can make the lower part of the equation equal to 18, which is 4.
We can even find the y value by making it equal to 10, which is 3.
