Area of triangle is .

Step-by-step explanation:

Here we have  , Triangle ABC is a right triangle  The length of BC is 5 units. We need to find the  area of ABC  .Let's find out:

Given in the picture is a right angled triangle

The coordinates of A are (-9,10) and B are (7,-2) and C is (4,-6)

Given that BC = 5 units

AB = distance between A and B

distance between two points (-9,10) and (7,-2)

⇒

⇒

⇒

Thus if we consider BC as base then AB is the height

Area of triangle

⇒

⇒

⇒

Therefore , Area of triangle is .

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
