Question

10. The area of trapezium of height 10 cm is
175 sq. cm. If one of the parallel sides measures
20 cm, find the length of the other parallel side.​

Answer 1

Step-by-step explanation:

Area of trapezium =175sq.cm

Distance betwwwn the prallel sides =10cm

One prallel side=20cm

Area of trapezium = 1/2× sum of prallel sides ×distance between them

here,

175=1/2×20+x×10

175=100+5x

5x=175-100

x=75/5

x=15

The another prallel side =15cm
