h2=2.1 cm. Find the area

Answer 1

Hello my name is romit

And here is your answer

According to question

Area of quadrilateral =

1/2×d×(h1+h2)

1/2×7

Answer 2

Area of quad. =1/2 × any diagonal × (sum of 2 perpendiculars which is drawn on that diagonal)

So,

Area of PQRS

= 1/2 × d × ( h1+ h2 ) sq. units

1/2 × 7 × ( 4.2 + 2.1) cm^2

= 22.05 cm^2
