Question

find the perimeter of triangle with diagonal 17cm and length of one side is 15 cm​

Answer 1

Answer:

46cm

Step-by-step explanation:

We know that 17cm is the hypotenuse of a right triangle with one side being 15cm.

So from the Pythagorean theorem we know that 17^2 - 15^2 will equal the square of the other side. 289 - 225 = 64 which is 8^2.

Therefore the rectangle has sides of 8 and 15.

Area is 120 cm^2 and perimeter is 46 cm.
