Question

The area of a right triangle is 315 square meters. The height of the right triangle is 15 meters. What is the length of the hypotenuse of the right triangle rounded to the nearest meter? No points given without showing your work.

Answer 1

Answer:

45 metres

Step-by-step explanation:

You have to get the base to answer the question.

Do this by dividing 315 by 15 then timesing by 2

You get 42.

Do 42^2 = 1764

Do 15 ^2 = 225

Because you want the hypotenuse you add them

1764 + 225 =1989

Do the square root of 1989 which is 45 to the nearest metre

Answer 2

Answer:

25.80

Step-by-step explanation:

Area = 315 $m^{2}$

Area = l*b

315 = 15 *b

b= 315/15

b = 21

From Right angled Triangle ,

Hypotenuse square = side square + side square

$x^{2}$ = $21^{2}$ + $15^{2}$

$x^{2}$ = 441 + 225

$x^{2}$ = 666

apply sq root on both sides, the we get

$\sqrt{x^{2}} = \sqrt{666}$

x= 25.80
