Let the width = x then we have that length = 2x + 5 and also that:
x + x + 2x + 5 + 2x + 5 = 70
6x + 10 = 70
6x = 60
x = 10
Therefore width = 10ft and length = 25ft
Answer:
58
Step-by-step explanation:
PEMDAS
The perimeter is the total measurement of all the sides together.
P = 82
Perimeter is side + side + side and so on.
So here is what we have.
15.4 + 16.2 + 28.7 + d = 82
Add up what you have now
60.3 + d = 82
Subtract 60.3 from both sides to get D
d = 82 - 60.3
d = 21.7
