Question

find the are of quadrilateral pqrs qs= 5 cm , RM = 2.5 cm and pn = 1.5 cm tell me this ​

Answer 1

$\huge{\underline{\underline{\bold{\mathtt{\purple{✍A{\pink{N{\green{S{\blue{W{\red{E{\orange{R✍}}}}}}}}}}}}}}}}$$\huge{\rightarrow}$

• Area of quadrilateral = Area of triangle RQS + Area of triangle PQS .

___________________

Area of triangle RQS = 1/2 × b × h

⟹ 1/2 × 5 × 2.5

⟹ 6.25 cm² .

Area of triangle PQS = 1/2 × b × h

⟹ 1/2 × 5 × 1.5

⟹ 3.75 cm²

_______________

Now ,

Area of quadrilateral = 6.25 cm² + 3.75 cm²

= 10 cm²
