Question

area of trapezium of height 4 centimetre is 32cm square One of The parallel sides of this trapezium is 6 cm Find the length of other parallel side

Answer 1

let the other parallel sidde be x cm
area of trapezium=1/2×sum of parallel side ×height
32=1/2×(6+x)×4
8=1/2×(6+x)
16=6+x
x=10
hence other parallel side is 10 cm

Answer 2

Let the leangth of other parallel side be x
Area of trapezium => 1/2 × sum of // side × height
32cm² => 1/2 ×(6 + x ) × 4
64 => (6+x) ×4
6+x=> 64/4
6+x => 16
x=> 16-6 => 10 cm
