Question

two parallel sides of a trapezium are 58 cm and 42cm . the other two sides are of equal length which is 17 cm. find the area of trapezium.​

Answer 1

Step-by-step explanation:

height of trapezium

( h)^2 = 17^2 - 8^2

289-64 = 225

h = 15 cm

area of trapezium =

1/2 * sum of parallel sides* height

= 0.5*(42+58)*15 = 750 cm^2

Answer 2

Step-by-step explanation:

42+2ae=58

=8ans.

√17=√8+√x

=√225

=15and.

area of trapezium=1/2×(a+b)h

=1/2×(58+42)15

=100/2×15 =750cm2
