Area of triangle = 1/2 * base * height
= 1/2 * 8 * 4
= 16 sq cm
Answer:
Triangle is obtained by joining in points & area of triangle is 16 unit²
Step-by-step explanation:
Given: Points A( -3 , 0 ) , B( 5 , 0 ) , C( 0 , 4 )
To find: Area of figure obtained by joining them
After plotting given points.
Figure obtained is attached.
We get Triangle by joining these points.
Area of Triangle
Base, AB = 5 + 3 = 8 unit
Height, CO = 4 unit
Area of Triangle
= 4 × 4
= 16 unit²
Therefore, Triangle is obtained by joining in points & area of triangle is 16 unit²
