7 and 10 because

perimeter you add all sides together like :

7 +7 +10 +10

14+20

34 (which checks out)

and then for area you multiply length and width and 7 x 10= 70 which checks out

Step-by-step explanation:

A = L * W
A = 70

70 = L * W

P = 2(L + W)
P = 34

34 = 2(L + W)
34/2 = L + W
17 = L + W
17 - W = L

70 = L * W
L = 17 - W

70 = W(17 - W)
70 = -W^2 + 17W
W^2 - 17W + 70 = 0
(W - 10)(W - 7) = 0

W - 10 = 0        L = 17 - 10
W = 10              L = 7

W - 7 = 0          L = 17 - 7
W = 7               L = 10

so either the width is 10 meters and the length is 7 meters OR the width is 7 meters and the length is 10 meters
