Find the perimeter of a isosceles right triangle having area of 200 CM square

miv72 [106K]

Answer:

The perimeter of the isosceles right triangle is 68.28 cm.

Step-by-step explanation:

Given;

area of the isosceles right triangle, A = 200 cm²

let the two equal sides of the triangle = base (b) and height (h)

Area of the isosceles right triangle is calculated as;

$A= \frac{1}{2} bh \\\\But, b = h\\\\A = \frac{1}{2} b^2\\\\200 = \frac{1}{2} b^2\\\\400 = b^2\\\\\sqrt{400} = b\\\\20 \ cm = b$

let the hypotenuse side of the isosceles right triangle = c

c² = b² + h²

c² = 20² + 20²

c² = 800

c = √800

c = 28.28 cm

The perimeter of the isosceles right triangle is calculated as;

P = b + h + c

P = 20 cm + 20 cm + 28.28 cm

P = 68.28 cm

Therefore, the perimeter of the isosceles right triangle is 68.28 cm.

What is the thoerema of Pitagora ?

stellarik [79]

The Pythagorean equation relates the sides of a right triangle in a simple way, so that if the lengths of any two sides are known the length of the third side can be found. Another corollary of the theorem is that in any right triangle, the hypotenuse is greater than any one of the other sides, but less than their sum.

hope this helped:)
