The perimeter equation for a rectangle is two times the base plus two times the height.
2B + 2H=P

Plug in the known values and solve for x.
2(2x) + 2(x+1)=53
4x+2x+2=53
6x=51
x=8.5

Now that we know what x is, put it back into the formula for the height of the rectangle to find the final answer.
H= x+1
H=8.5+1
H=9.5 ft

MrMuchimi

Answer: 50%

Step-by-step explanation:

Let x = Total dishes.

Dishes from China = $\dfrac38x$

Dishes from Japan = $12.5\% \text{ of }x= 0.125x$

Total dishes from China and Japan = $\dfrac38 x+0.125x=0.375x+0.125x=0.5x$

Dishes from other countries $= x- 0.5x= 0.5x$

Percent of dishes from other countries= $\dfrac{0.5x}{x}\times100\%= 50\%$

Hence, dishes from other countries = 50%
