A 70-meter path surrounds a rectangular garden. The width of the garden is two-thirds its length. Find the length and the width.

bagirrra123 [75]

$width=\frac{2}{3}length\\\\
70=2width+2length\\\\
70=2length+2(\frac{2}{3}length)\\\\
70=2length+\frac{4}{3}length\\\\
70=\frac{10}{3}length\ \ | divide\ by\ \frac{10}{3}\\\\
70*\frac{3}{10}=length\\\\
length=21m\\\\
width=\frac{2}{3}*21=14m

Step-by-step explanation:

Pythagoras' theorem for the smallest one :

$c^2 = 4^2 + 6^2$

$c^2 = 16 + 36$

$c^{2}$ = 52

Pythagoras' theorem for the middle one :

$b^{2}$ = $6^{2}$ + $a^{2}$

Pythagoras' theorem for the biggest one :

$(4+a)^2 = c^2 + b^2$

$16 + 8a + a^2 = 52 + b^2$

Using the formula before (for $b^2$ ) it becomes :

$16 + 8a + a^2 = 52 + (6^2 + a^2)$

$16 + 8a + a^2 = 52 + 6^2 + a^2$

$16 + 8a = 52 + 6^2$

16 + 8a = 52 + 36

16+8a = 88

8a = 88-16

8a = 72

$a = \frac{72}{8}$

a = 9

Verifying :

$b^2 = 6^2 + a^2$

$b^2 = 36 + 81$

$b^2 = 117$

$b^{2}$ = 117

The biggest one :

$(4+a)^2 = c^2 + b^2$

$(4+9)^2 = 52 + 117$

$13^2 = 169$

astra-53 [7]

Answer:

your answer is 10/3 (fraction)

Step-by-step explanation:

120-40=80

4 x 6=24

80/24=

first divide both sides by four and get 20/6
then divide by 2 to get 10/3 (fraction form)
