Answer: P=130
2W +2L=130
2(31) + 2(34)=130
W=31
L=34
Step-by-step explanation:
P=130
2L + 2W
W=L-3
Add all of the sides together to get perimeter.
2(L-3) + 2L=130
2L-6+2L=130
4L-6+6=130+6
4L=136
4L/4=136/4
L=34
W=L-3
W=34-3
W=31
Answer:
Thx for the points
Step-by-step explanation:
(1/6) / (1/4) = x / 1....1/6 acre to 1/4 hr = x acres to 1 hr
cross multiply because this is a proportion
(1/4)(x) = (1/6)(1)
1/4x = 1/6
x = 1/6 * 4/1
x = 4/6 which reduces to 2/3....so she can mow 2/3 of an acre in 1 hr <=
