Question

the area of trapezium shaped field is 480m2 the distance between two parallel sides is 15 m and length of one of the parallel sides is 20m.what is the length of the other parallel side?

Answer 1

$<tt><b>$
______________________
Solutions :-

Given :

Area of trapezium = 480m²
Height = 15 m
Length of one of the parallel side = 20 m

Let the length of other parallel sides be x

We know that,

Area of trapezium = (sum of parallel sides)/2 × height

A/q

=> 480 = (20 + x)/2 × 15
=> 480/15 = (20 + x)/2
=> 32 × 2 = 20 + x
=> 64 - 20 = x
=> x = 44

Hence,
The length of the other parallel side = 44 m

Answer 2

HERE IS YOUR ANSWER :-


$\underline{GIVEN}$


Area of trapezium = 480 m²


Distance between parallel sides i.e. height = 15 m


One of the parallel side = 20 m


$\underline{\:TO\:FIND}$


Lenght of other parallel side = ?


$\underline{SOLUTION}$


Let the lenght of parallel side be " x m " .


$we \: know \: that \: \\ \\ \\ area \: of \: trapezium = \frac{1}{2} \times sum \: of \: parallel \: sides \times height \\ \\ \\ 480 = \frac{1}{2} \times (x + 20) \times 15 \\ \\ \\ 480 \times 2 = 15(x + 20) \\ \\ \\ 960 =15( x + 20 )\\ \\ \\ \frac{960}{15} = x + 20 \\ \\ \\ x = 64 - 20 \\ \\ \\ x = 44$


$<b>THE LENGHT OF OTHER PARALLEL SIDE IS 44 m}}$
