Answer: 13cm
Step-by-step explanation:
In terms of y:
The area of a right angled triangle is base x height / 2
This means that:
y x 15.9 ÷ 2 = 103.35
Now it can be solved as a normal equation:
103.35 x 2 = 206.7
y x 15.9 = 206.7
206.7/15.9 = y
y = 13cm
Answer:
The other side is 13 cm.
Step-by-step explanation:
The area of a triangle is (1/2)b*h.
(1/2)b*h = 103.35 cm^2
We are told that one of the sides containing the right triangle measures 15.9 cm. It makes no difference if we call that measure the base of the height (just turn the triangle - see the attached image).
Therefore, let's call it b. b = 15.9 cm
(1/2)b*h = 103.35 cm^2
(1/2)(15.9 cm)*h = 103.35 cm^2
(7.95 cm)*h = 103.35 cm^2
h = 13 cm
