Answer:
39 meters
Step-by-step explanation:
We know the bottom distance ( 20-13) = 7
And we know the height 15-0 =15
We can use the Pythagorean theorem to find the hypotenuse
a^2 + b^2 = c^2
7^2 + 15^2 = c^2
49+225 = c^2
274 = c^2
Taking the square root of each side
sqrt(274) = c
We want the perimeter
a+b+c
7+15+sqrt(274)
22+sqrt(274)
22+16.55294536
38.55294536
Rounding to the nearest meter
39 meters
Answer:
[tex]\huge \boxed{\mathrm{39 \ meters}}[/tex]
Step-by-step explanation:
The perimeter of the right triangle is required.
The base of the triangle is 7 units.
The height of the triangle is 15 units.
The hypotenuse can be found through Pythagorean theorem.
a² + b² = c²
7² + 15² = c²
49 + 225 = c²
274 = c²
c = [tex]\sqrt{274}[/tex]
Adding all the three sides of the right triangle to get the perimeter.
P = a + b + c
P = 7 + 15 + [tex]\sqrt{274}[/tex]
P = 38.552945...
The perimeter of the right triangle is 39 meters rounded to nearest meter.
