Question

If the perimeter of a trapezium is 50 cm and its non-parallel sides are equal and 10 cm each and its altitude is 8 cm , find its area.

Answer 1

Answer:

120 $cm^2$

Step-by-step explanation:

Perimeter =50cm

a + b + 10 + 10 = 50

a + b = 30 cm

h = 8cm

Area = ½ (a+b) * h

        = ½ * 30 * 8

        = 30 * 4

        = 120 $cm^2$
