Question

Find the area of a trapezium, if it's parallel sides are 7cm and 8cm and the distance between the parallel sides is 4cm​

Answer 1

Answer:

30cm²

Step-by-step explanation:

Height, h=4cm

One parallel side, a=7cm

Other parallel side, b=8cm

Area of trapezium = h(a+b)/2

                              =4(7+8)/2

                              =30cm²

Answer 2

Step-by-step explanation:

Parallel sides of a trapezium a = 7cm and b = 8cm

distance between them = height = 4cm

Area of a trapezium = 1/2 × h (a + b)

= 1/2 × 4 × (7 + 8)

= 2 ( 15)

= 30cm²
