The area of triangle is 13905.5 cm square when height is 137 cm and bae is 203 cm.
Given that,
There is a triangle with height 137 cm and base 203 cm.
We have to find the area of triangle.
We know,
The entire area filled by a triangle's three sides in a two-dimensional plane is referred to as the triangle's area. A straightforward formula can be used to get the area of a triangle by multiplying the sum of the base and height by two.
Area of triangle =1/2×b×h
Area of triangle =1/2×137×203
Area of triangle =1/2×27811
Area of triangle =13905.5
Therefore, The area of triangle is 13905.5 cm square when height is 137 cm and bae is 203 cm.

Answer:
(-2, -3)
Step-by-step explanation:
90° clockwise rotation:
(x, y) -----> (y, -x)
Let's apply this to our coordinates:
(x, y) -----> (y, -x)
(3, -2) -----> (-2, -3)
Simply make the old y-coordinate the new x-coordinate, and make the old x-coordinate negative and make the new y-coordinate.
Therefore, the coordinate of the new point is (-2, -3).
