Answer:
The correct option is B.
Step-by-step explanation:
The area of triangle is
Where, b is the base of the triangle and h is the height of the triangle.
It is given that the base of the triangle is 10 inch and the height of the triangle is 14 inch.
The area of given triangle is
Therefore the area of triangle is 70 square inch and the option B is correct.
Equation of an ellipse
→having center (0,0) , vertex ( and covertex
and focus
is given by:
As definition of an ellipse is that locus of all the points in a plane such that it's distance from two fixed points called focii remains constant.
Consider two points (a,0) and (-a,0) on Horizontal axis of an ellipse:
Distance from (a,0) to (c,0) is = a-c =
Distance from (-a,0) to (c,0) is = a + c =
a -c + a +c
= a + a
= 2 a →(Option A )
