Answer :

Given. PQRS is a trapezium.

PQ = 8 cm, RS = 4.5 cm , QR = 5 cm, PR = 6 cm


Formula used. Area of trapezium = × height × sum of parallel sides Area of trapezium = × height × (PQ + SR)


Steps of Construction


Step 1 : Draw a line PQ of 8cm


Step 2 : Make an arc of 6cm from point P and 5cm from point Q



Step 3 : Mark the intersection point as R and join PR and QR



Step 4 : Draw a ray RS’ parallel to PQ from point R


Step 5 : Make an arc of 4.5cm on ray RS’ from point R and name intersection point as S



Step 6 : Join point S and P to form trapezium PQRS



Step 7 : Draw a perpendicular on PQ from point R and name the intersection point as E



Area of trapezium = × height × (PQ + SR)


= × RE × (PQ + SR)


= × 3.8cm × (4.5cm + 8cm)


= 23.75cm2


Conclusion. Hence; Trapezium PQRS is constructed and its area is 23.75cm2
