Question

area of trapazium shape field is 480m 2,the distance between two parallel sides is 15 m and one of the paellel side is 20 m . find the other parellel side.

Answer 1

area of trapezium= 1/2 × h × b1 +b2
480=1/2×15×20+x
480=1/2×300+x
480/150=x
x= 3.2 m
therefore another parallel side is 3.2 m

Answer 2

area of trapezium=1/2*b*h
$1 \div 2 \times b \times h$
$480 = 1 \div 2 \times 15 \times 20 = 150$
150 is the answer
