SOLUTION:—
Area of the given trapezium = 1.6 m²
Given altitude = 10 dm , dm into m = (10 / 10) m = 1m
Formula of the area of the trapezium = 1/2 × (sum of parallel sides) × altitude
let the sum of parallel sides be x
=> 1/2 × x × 1 = 1.6
=> x = 1.6×2
=> x = 3.2 m²
According to question:—
Given length of the longer side = 8 dm, dm into m = (8/10) m = 0.8 m
therefore, the length of another side = (3.2m - 0.8m)
= 2.4 m
Hence, the length of the other side of the trapezium is 2.4m .
