Question

In rectangle PQRS PS = 18cm and SR = 9cm. Find area of triangle ABC

Answer 1

Answer:

The area is=81cm square

Answer 2

Area of PSQR=PQBA

( both have that same base and are between the same parallel lines)

So PQBA = 18cm×9cm= 162cm^2

Triangle ABC will be half of PQBA because triangles areas are half of the //gms with same base and between same // line

So ABC is 81cm^2
