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

Answer:

CD ≈ 26.0 cm

Step-by-step explanation:

using the sine ratio in right triangle ABD

sin35° = $\frac{opposite}{hypotenuse}$ = $\frac{AB}{BD}$ = $\frac{12}{BD}$ ( multiply both sides by BD )

BD × sin35° = 12 ( divide both sides by sin35° )

BD = $\frac{12}{sin35}$ ≈ 20.92 cm

using the sine rule in Δ BCD

$\frac{BD}{sinC}$ = $\frac{CD}{sinB}$ , that is

$\frac{20.92}{sin52}$ = $\frac{CD}{sin102}$ ( cross- multiply )

CD × sin52° = 20.92 × sin102° ( divide both sides by sin52° )

CD = $\frac{20.92sin102}{sin52}$ ≈ 26.0 cm ( to 3 significant figures )

d.Hector cannot afford to see the sumo tournament, because it would put him over budget by almost $12.

 Exchange rate $ 1.00 ¥ 94.153 Balance:
 Beginning Balance: $ 575.00 ¥ 54,137.98
 Kabuki performance $ 74.95 ¥ 7,056.77 ¥ 47,081.21
 Kaiseki dinner ¥ 8,745.00 ¥ 38,336.21
 Shopping $ 262.49 ¥ 24,714.22 ¥ 13,621.99
 Onsen visit ¥ 6,811.00 ¥ 6,810.99
 Museum visit ¥ 2,423.00 ¥ 4,387.99
 Sumo Tournament ¥ 5,488.00 ¥ -1,100.01

1,100.01 / 94.153 = $11.68 rounded up to $12.
