Answer:
The Length is 85 m
Step-by-step explanation:
? = l
68 = w
306 = P
The perimeter formula is P = 2(l+w) or P = (l+w) + (l+w)
306 = 2(l+68)
306 = 2l + 136
306 - 136 = 2l + 136 - 136
170 = 2l
[tex]\frac{170}{2}[/tex] = [tex]\frac{2l}{2}[/tex]
85 = l
Length is 85 m
306 m = perimeter
68 + 68 = 136
306 - 136 = 170
170 / 2 = 85
So therefore the width is 85 m
Check
68 + 68 + 85 + 85 = 306
136 + 170 = 306
306 = 306
68 + 68 = 136
306 - 136 = 170
170 / 2 = 85
So therefore the width is 85 m
Check
68 + 68 + 85 + 85 = 306
136 + 170 = 306
306 = 306
