Question

. The lengths of two parallel edges of a railway platform are 100 m and 132 m. Each of the remaining two non-parallel but equal sides
are 20 m long, then find the area of platform.
HELP ME PLEASE ​

Answer 1

the mesure of pareller side is respectly 100,132

the non pareller side is equal and their measurement is 20

to find the hight of parellogram

We use pythogorus theorem

h ki power 2+16 ki power 2=20 ki power 2

then,

h ki power 2+256=400

h ki power 2=400-256=144

h =✓144=12

h= 12

t now we find the valu of h =12

then ,

We use the formula tu find the area of trapezium

1/2h(a+b)

1/2×12(100+132)

6(100+132)

600+792

=1392 is the answer of the question.
