Question 133638
In a right triangle, one of the angles is a right angle—an angle of 90 degrees. A right triangle may be isosceles or scalene.

The formula to use is:

A = 1/2 times base times height

Let x = length of each side (base and height)

98 = 1/2(x)(x)

98 = 1/2(x^2)

Divide both sides by 1/2.

98 divided by 1/2 = x^2

196 = x^2

Take square root of both sides.

+ - 14 = x

Since we are looking for length of sides, we MUST REJECT a negative answer for x because distance CANNOT be negative.

So, x = 14.

This means that each side measures 14cm.
