Question

The sum of the parallel sides of a trapezium is 25cm and its area is 150cm. Find the altitude.​

Answer 1

Answer:

h = 12 cm

Step-by-step explanation:

Formula = $\frac{h(a+b)}{2}$

= $\frac{h(25)}{2}$

12.5h = 150

h = 12 cm

Answer 2

Answer:

Altitude is 12 cm

Step-by-step explanation:

Given,

the sum of parallel sides is 25 cm

the area of that trapezium is 150 cm

• Area of trapezium= 1/2 (sum of parallel sides)(altitude)

150 = 1/2 × 25 × h

h = 150 × 2/1 ÷ 25

h = 300/25

h= 12 cm

▪altitude = 12 cm
