Answer 1

Answer:

Step-by-step explanation:

Area of trapezium= 1/2×(Sum of parallel sides)×Height of the trapezium

Q7- Area = 180

      let on of the parallel side be =x

      length of other parallel side = x+6

      height =9

      180 = 1/2×(x+x+6)×9

       x= 17

       length of parallel sides = 17 & 23

Q8- Area = 9450

      let on of the parallel side be =x

      length of other parallel side = 2x

      height =84

      9450 = 1/2×(x+2x)×84

       x= 75

       length of parallel sides = 75 & 150

Q9- length of AB(height) = 15

       length of parallel sides = 54 & 42

      Area = 1/2*(54+42)*15 = 720cm²

Answer 2

Answer:

itna easy answer nhi hua satyam sharm aani chahiye.

length = perimeter

given three sides.

fourth side = perimeter - sum of three sides.

x = 130 - (54+19+42)

x = 15

area = sum of parallel side * height /2

area = (54+42)*AB/2

96 * 15/2

area = 48*15

= 720
