Question

The area of a trapezium is 385 cm square its parallel sides are in ratio 3:4 and the perpendicular distance between them is 11cm its longer side is

Answer 1

hello mate ...

here is your answer

area of trapezium=385cm2

let the parallel sides be 3x and 4x.

h=11cm

therefore,

$385 = 1 \div 2 \times h \times (a + b)$

$385 = 1 1\div 2(7x)$


$385 \times 2 \div 11 = 7x$


$7x = 70$


$x = 70 \div 7 = 10$


the longer side is 4 x.
4x= 4×7
=28cm.

hope it helps you
