In a right triangle 13

The height of the hypotenuse is 4.8cm. The hypotenuses are in the ratio 4:3. Calculate the perimeter and area of ​​a triangle.

Correct answer:

o =  24 cm
S =  24 cm2

Step-by-step explanation:

h=4.8 cm a:b = 4:3  S1 = S2  2a b = 2c h a b = c h  a (3/4a) = c h  3/4 a2 = c h  a2+b2 = c2 a2+(3/4a)2 = c2 a2+9/16a2 = c2 25/16a2 = c2 5/4a = c  3/4 a2 = (5/4a) h 3/4 a = 5/4 h  3 a = 5 h  a=35 h=35 4.8=8 cm b=43 a=43 8=43 8=424=6 cm  c=45 a=45 8=45 8=440=10 cm  o=a+b+c=8+6+10=24 cm
