In a multi digit whole number a digit in one place represent blank times what it represents in the place to its left

Take the example 54321

Start on your right. Each digit to the left of 1 represents something that is 10 times bigger than the units digit. So for example 2 is 2*10 and 1 is just 1.

But you want to know what happens going the other way. You are looking at the tens digit (say) and you want to know what to say about a number where you start in one place and look at a number to the left of that number.

The number where you are is 1/10 the place value of the number to it's left.

this doesn't make sense lol

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk
