Find the area of the following triangle 12 SolutionAnswer t

Find the area of the following triangle.

12 -?

Answer to the questions is as follows:

b. This is isoceles triangle, So adj sides are equal. And this is a right triangle we have:

So, a^2 + a^2 = 144, where a is any of the adjucent sides. So,

2*a^2 = 144

a^2 = sqrt(72) = 6sqrt(2)

So, area of triangle = .5*6sqrt(2)*6sqrt(2) = 36

The Area of paralleogram is given by a*b where a is slant length and b is the base.

So, the Answer is 3*4 = 12 units square

4. Area of triangle = .5*base*height = .5*4*3 = 6 units square
