Question

The parallel area of a sides of trapezium are 9 cm and 7 cm and its area is 80 CM square find its altitude​

Answer 1

Answer:

let the altitude be h

given parallel sides are 9cm and 7cm

area=80 sq. cm

b. t. p

1/2(9+7) X h=80

16h=160

h=10

height=10cm

Answer 2

Answer:

1st side 7cm

2nd side 9cm

Step-by-step explanation:

area of trapezium =1/2*h(a+b)

80=1/2*h(7+9)

80=1/2*h*16

80=8

80/8=10

Hence altitude=10
