Question

The area of a trapezium is 105 cm2 and the height is 7cm2 . if one of the parallel sides is longer than the other by 6 cm, find the lengths of 2 parralel sides

Answer 1

Answer:

Hence the length of the of shorter side =12 m And the longer side is =12+6=18 cm

Step-by-step explanation:

GIVEN:Area of Trapezium =105 Cm² And h= 7 cm

Let the length of shorter side be x cm

Then the length of longer side is (x+6)cm

Therefore the sum of parallel sides =x+x+6=2x+6.

Now, area =105

=>½×7×(2x+6)=105

=>2x+6=105×2/7=30

=>2x=30-6=24

=>x=12cm

Hence the length of the of shorter side =12 m And the longer side is =12+6=18 cm
