**Question 1.**

**Solution:**

In trapezium ABCD,

Length of parallel sides

AB = 24 cm, DC = 20 cm

and distance between them = 15 cm

**Question 2.**

**Solution:**

Parallel sides of a trapezium ABCD are

l1 = 38.7 cm. and l2 = 22.3 cm

**Question 3.**

**Solution:**

Parallel sides of the trapezium = 1 m, 1.4 m

**Question 4.**

**Solution:**

Area of trapezium = 1080 cm²

Lengths of parallel sides are

l1 = 55 cm and l2 = 35 cm

Let h be the distance between them

**Question 5.**

**Solution:**

Area of trapezium shaped field = 1586m²

Distance between parallel sides = 26 m

Sum of the parallel sides = \(\frac { Area\times 2 }{ Altitude }\)

= \(\frac { 1586\times 2 }{ 26 } \) = 122 m

One side = 84 m

Second side = 122 – 84

= 38 m

**Question 6.**

**Solution:**

Area of trapezium = 405 cm²

Ratio in parallel sides = 4:5

and distance between them = 18 cm

**Question 7.**

**Solution:**

Area of trapezium = 180 cm²

Height (h) = 9 cm.

Let l1 and l2 be the parallel sides,

**Question 8.**

**Solution:**

Let one of parallel sides = x

Then second sides = 2x

Area = 9450 m²

Distance between them = 84 m

**Question 9.**

**Solution:**

Perimeter of trapezium ABCD = 130 m

AB ⊥ AD and BC

BC = 54 m, CD = 19 m, AD = 42 m

**Question 10.**

**Solution:**

In the given trapezium ABCD, AC is

**Question 11.**

**Solution:**

In trapezium ABCD,

**Question 12.**

**Solution:**

In trapezium ABCD,

AB || DC

AB = 25 cm DC = 1 cm

AD = 13 cm and BC = 15 cm
