Question

pratima made a triangle ABC in which base AC =10CM AND ALTITUDE IS 3CM AND TRIANGLE DEF IN WHICH DE =10CM AND ALTITUDE =6CM THEN SHE JOINED THE TRIANGLES SUCH THAT A COINCIDES WITH D AND C COINCIDES WITH E. FIND THE AREA OF THE QUADRILATERAL THUS FORMED

Answer 1

45 cm is ur answer ..................

Answer 2

Step-by-step explanation:

Area of Triangle ABC= 1/2 × base × corresponding altitude

= 1/2 × 10 × 3

= 5 ×3

= 15 cm

Area of Triangle DEF = 1/2 × base × corresponding altitude

= 1/2 × 10 × 6

= 5 × 6

= 30

Area of quadrilateral = Area of Triangle ABC + Area of Triangle DEF

= 15 + 30

= 45 cm
