Question

The area of a Trapezium is 780 CM square and perpendicular distance between parallel sides is 13 cm. Find the length of other parallel sides is one of them is 54cm long.

Answer 1

Answer:

66 cm

Step-by-step explanation:

Area of Trap. = 1/2(a+b)*h

780 cm² = 1/2(54+x)*13

780/13= 1/2(54+x)

60 = 1/2(54+x)

60*2 = 54+x

120 = 54+x

x= 120-54

x= 66 cm

Answer 2

Answer:

6cm

Step-by-step explanation:

area of trapezium=1/2*(sum of parallel sides)*distance between them.

let the length of other parallel side =x

ATQ,

780=(54+x)*13

780/13=54+x

60=54+x

60-54=x

x=6cm

therefore, length of other parallel side=6 cm
