Question

the length of the parallel sides of a Trapezium are in the ratio 3 is to 5 and the distance between them is 10 cm if the area of a Trapezium is 120 CM square find the length of its parallel sides

Answer 1

Heya!
--------

=============================================================

♦Let the sides of the Trapezium be 3x and 5x respectively !

♦Area of Trapezium=> ½ ( b1 + b2 ) × H

Therefore ,
--------------

120 = ½ ( 3x + 5x ) × 10

120 = 5(8x)

120 = 40x

x=>> 3
======

↪Length of the parallel sides are 3(3) = 9cm and 3(5) = 15 cm !!

------------------------------------------------------------------------------------------------

Answer 2

Hey Friends,
______________________________

Let the parallel side be 3x & 5x.
Hight=10 cm.

Area of Trapezium = 1/2(3x+5x)×10
120=8x/2×10
120=40x
x=3

Parallel side are 3×3=9 cm & 5×3=15 cm.

HOPE IT'S HELP YOU!!!!!!
