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

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;

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.

i think the answer is b.
