The area of a rectangular concrete patio is 70 square meters. the perimeter is 34 meters. what are the dimensions of the patio?
Finger [1]
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

Which number is between 7/11 and 0.75( the 75 is repeating)
AlekseyPX

Convert 7/11 to a decimal value.

7 divided by 11 = 0.636364

Subtract 0.636364 to 0.757576 and divide the difference by 2.

Following the equation, 0.636364 - 0.757576 = 0.121212.

<span>0.121212 divided by 2, the quotient is 0.06 (06 is repeating) </span>
