Question

If the perimeter of a trapezium is 104 cm, its non parallel sides are 18 cm and 22 cm, then the sum of its parallel sides are

Answer 1

Answer:

perimeter of trapezium = sum of its all sides

if the perimeter is 104 cm

then perimeter = sum of all sides

104 cm= 18 +22 + sum of parallel sides

sum of parallel sides = 104 - 40 cm

sum of parallel sides = 64 cm

Answer 2

Answer:

$p(trapezium) = sum \: of \:sides \\ p(trapezium)= a + b + c + d \\ \: \: = 104 = a + 22 + c + 18 \\ = 104 = a + c + 40 \\ = 104 - 40 = a + c \\ 64 = a+c \\ thre \: sum \: of \: parallel \: side \: = 64$
