Answer:
A) 7 meters
Step-by-step explanation:
As you know the length of the rectangle you would first multiply the length of 35 by 2, which gives you 70. This is because the perimeter is the sum of all the lengths and that a rectangle has 2 sets of different identical lines. Then you would minus 70 from 84, which gives you 14. This is because you are now finding out the sum of the set of widths. Then you would divide 14 by 2 to find the width, which gives you 7 meters.
1) Multiply 35 by 2.
[tex]35*2=70[/tex]
2) Minus 70 from 84.
[tex]84-70=14[/tex]
3) Divide 14 by 2.
[tex]14/2=7 meters[/tex]
