Answer:
The equation can be expressed as;
x+y=71 where,
Lengths of two equal sides=x=22 m
Lengths of longer side=y=27 m
Step-by-step explanation:
The total perimeter can be expressed as;
Total perimeter=Total length of the equal sides+total length of the longer side
where;
Total perimeter=71 m
Total length of each of the equal sides=x m
Total length of longer side=y=(x+5) m
replacing;
x+y=71...equation 1
71=(2×x)+(x+5)
2 x+x=71-5
3 x=66
x=66/3
x=22 m
y=x+5=22+5=27 m
Lengths of two equal sides=22 m
Lengths of longer side=27 m
Equation;
x+y=71
there would be 29 pencils left because 3 * 12 is 36 minus 7 is 29

you add all the variables
Okay, so here is a small lesson on rounding. When you round you MUST know the place value of each number. Ones, tens, hundreds, thousands, millions.
So, when we look at this number what do we have in the ones place --there is a 0 -- in the tens place we have a 9 and in the the thousands place we have 5. to round this number look at the tens place. if the number is greater than 5 you round 73590 to 73600, if it is 4 and lower it stays the same and the numbers behind change to zero--> like so 73500. But for this problem it would round up to 73600.
