A rectonale has an area of
36cm and width 3cm. Find it's perimeter.

Step-by-step explanation:

Area of a rectangle ( A ) = 36 cm²

Width of a rectangle ( w ) = 3 cm

:

Perimeter of a rectangle ( P ) = ?

First, finding the length of a rectangle ( l ) :

Length of a rectangle = 12 cm

Now, finding the perimeter of a rectangle having length of 12 cm and width of 3 cm

Perimeter of a rectangle = 30 cm

Hope I helped!

Best regards! :D

i understand 100% 10/10 hit or miss?

step-by-step explanation:

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
