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.

Final 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
