Try this option:
According to property such triangle
1. area=0.5*a*b, where a and b - the sides of angle 90°.
Using this equation: 180=0.5*40*b, ⇒ b=9.
2. c²=a²+b², ⇒c=√(9²+40²)=41 - the third side of the triangle;
3. Perimeter=a+b+c=9+40+41=90 cm.
answer: 90 cm.
Answer:
The width is 9.5 ft
Step-by-step explanation:
Perimeter for a rectangle is given by
P = 2 (l+w)
43.8 = 2 (12.4+w)
Divide each side by 2
21.9 = 12.4+w
Subtract 12.4 from each side
21.9-12.4 = w
9.5 = w
The width is 9.5 ft
