Calculating the area and the perimeter. The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle.

Answer:

x = 4

Step-by-step explanation:

Using the sine ratio on right triangle KJL

and the exact value sin30° = $\frac{1}{2}$

sin30° = $\frac{opposite}{hypotenuse}$ = $\frac{JL}{KL}$ = $\frac{JL}{8\sqrt{2} }$ = $\frac{1}{2}$ ( cross- multiply )

2JL = 8 $\sqrt{2}$ ( divide both sides by 2 )

JL = 4 $\sqrt{2}$

---------------------------------------------------------

Using the sine ratio in right triangle JLM

and the exact value sin45° = $\frac{1}{\sqrt{2} }$

sin45° = $\frac{opposite}{hypotenude}$ = $\frac{LM}{JL}$ = $\frac{x}{4\sqrt{2} }$ = $\frac{1}{\sqrt{2} }$ ( cross- multiply )

x × $\sqrt{2}$ = 4 $\sqrt{2}$ ( divide both sides by $\sqrt{2}$

x = 4

<span>Alex is 1.6 m tall
and
Noah is 1.5 times as tall as Alex
= 1.6 m x 1.5 = 2.4m

1 m = 100 cm
2.4 m = 2.4 x 100 = 240 cm
