Take all the zero's away and multiply the numbers that are left.
which is 1*1=1 now add all of the zeros to that one which will turn it into
10000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
which is the answer
10/2.5= 4 the answer is 4 meters because you just divide them.
The perimeter of RSTU can be calculated alone without the help of MNPQ. It would be just 2(4) + 2(3) = 14 units. However, it would be much sensible if you want to find the parameter of the bigger rectangle. Since they are similar, you could use ratio and proportion.
(length/width)∨MNPQ = (length/width)∨RSTU
(x/9) = (3/4)
x = 6.75 units
Thus the perimeter of MNPQ is 2(6.75) + 2(9) = 31.5 units
Im not sure but x-3 might determine finding what x equals
