Question

Find the area of a Trapezium whose parallel sides are 25 cm , 13 cm and the non-parallel sides are 15 cm each

Answer 1

formula = 1/2 × sum of all parallel sides × height

height = 6 cm
area = 1/2×(25+13)×6
=38×3=114 cm cube

Answer 2

Area = ( a + b ) / 2 x Height
a = 25
b = 13
height = 25 - 13
           = 12
12 /2 = 6
15^2 - 6^2 = 189
square root 189 = 13.75
area = (25 +13) /2 x 13.75
        = 261.25
