Question

What is the perimeter and area of a triangle that measures 5, 5, and 5 square root 2?

Answer 1

Perimeter: `10+5sqrt(2)`
Area: `12 1/2` sq.units

Explanation:

The dimensions given are those of a standard right-angled triangle with two `45^@` angles.

The perimeter is simply the sum of the lengths of the given sides.

Since this is a right-angled triangle, we can use the non-hypotenuse sides as a base(`b`) and height(`h`).

`"Area"_triangle = 1/2 bh= 1/2*5*5 = 25/2=12 1/2`
