Question

the area of a right triangle region is 38.5cm2 if one of the sides containing the right angle is 11cm then find the other side

Answer 1

let the side containing right angle be the base.
area of Δ=1\2 * base * height
   38.5    =1\2*11*height
 385*2÷11*10= height
7cm  = height
          if you want to find the hypotenuse also you can use the pythagoreus theorum,

H²=base²+perpendicular²
H²=11²+7²
H²=121+49
H²=170
H=√170 CM
                    here H is hypotenuse

Answer 2

Answer:

Step-by-step explanation:

the area of a right angled triangle is 1/2 bh

given

1/2 (14.8)(h) = 129.5

7.4(h)=129.5

h=17.5

The other side is 17.5cm
