Question

the area of trapezium is 45 CM square if its height is 6 cm and the length of one of its base is 9 cm find the length of its other base​

Answer 1

Answer:

6cm

Step-by-step explanation:

area of trapezium: 1/2*(S1 +S2)*h

Here, height, h=6

area=45

parallel side 1, S1= 9

Therefore, 45 = 1/2*(9+S2)*6

=> 45 = (9 + S2)*3

=>45/3= 9 + S2

=>15-9= S2

Therefore, S2= 6 cm

Answer 2

Answer:

6 cm

Step-by-step explanation:

Let the other base =x

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

45 =1/2(9+x)×6 (6 is divide by 2= 3)

45 =(9+x)×3

45 =27+3x

3x =45-27

3x =18

x =18/3

x=6cm
