Right triangle

The legs of the right triangle are in the ratio a:b = 2:8. The hypotenuse has a length of 87 cm.

Calculate the perimeter and area of the triangle.

Correct answer:

o =  192.503 cm
S =  890.4706 cm2

Step-by-step explanation:

c=87 cm a:b = 2:8 c2 = a2+b2 c2 = a2+(8/2   a)2 c2 = a2+(8/2)2 a2 c2 = a2 (1 +(8/2)2 )  a=c/1+(8/2)2=87/1+(8/2)221.1006 cm  b=a 28=21.1006 2884.4024 cm  o=a+b+c=21.1006+84.4024+87=192.503 cm
S=2a b=221.1006 84.4024=1715138 cm2=890.4706 cm2
