Question

Find the value of unknown




​

Answer 1

h ×(18+24)/2= 273 cm²

h×42=273 cm²

h=273/42 =81/14 cm

=5.78 cm

Answer 2

Given:

☛ area of trapezium = 273 cm²

☛ parallel sides:

• AB = 24 cm
• CD = 18 cm

To Find:

☛ value of h

Solution:

We know,

☛ Area of trapezium = 1/2 × (sum of parallel sides) × h

➜ 273 = ( AB + CD ) / 2 × h

➜ 273 = (24 + 18)h / 2

➜ 273 = 42h / 2

➜ 21h = 273

➜ h = 273/21

➜ h = 13

Hence, Value of h is 13 cm
