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;
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.
Y=2x+3
put x =0 onetime then y=3
now put y =0 2x+3
x= -3/2

Answer: D. 94.25 in²
Step-by-step explanation:
To find the total area, we will break the shape up into two different parts.
[] The rounded part is 39.25 in². Let us assume the rounded part is exactly half of a circle.
Area of a circle:
A = πr²
Use 3.14 for pi:
A = (3.14)r²
Find the radius:
d / 2 = r, 10 / 2 = 5 in
Subsittue:
A = (3.14)(5)²
A = 78.5 in²
Divide by 2 since it is only half:
78.5 in² / 2 = 39.25 in²
[] The triangle is 55 in².
Area of a triangle:
A = b*h/2
A = 11 * 10 / 2
A = 110 / 2
A = 55 in²
[] Total area. We will add the two parts together.
55 in² + 39.25 in² = 94.25 in²
