Question

a Trapezium pqrs has two right angles at P and S measurement in centimetre are given as shown in the figure find the area of trapezium ​

Answer 1

Answer:

we know that

Area of trapezium=1/2*height*(sum of parallel side)

here, height=12cm

and, parallel sides are 20cm and 29cm. so put in the formula

hence area of trapezium is 294 CM.sq

Answer 2

Step-by-step explanation:

1.To find the area of the trapezium.

2.Do construction From point R,Draw RT perpendicular to PQ.

3.So Area of Rectangle PSRT =L×B

4.so 12×20=240 cm

5.so Area of the TriangleRTQ=1/2×base×height

6.1/2×9×12=54 cm

7.so Area of the Trapezium =Area of Rectangle - Area of Triangle=240+54=294 cm square

This is my easy way if we forget formulae
