Question

the area of a trapezium is 279 sq. cm and the distance between it's two parallel sides is 18 cm. if one of its parallel sides is longer than the other side by 5 cm, find the lengths of its parallel sides​

Answer 1

Answer:

13cm and 18cm

Step-by-step explanation:

area = 279 cm2

height = 18cm

1 side = x+5

2 side = x

according to the formula

= 1/2 × (x+x+5) ×18

2x+5 ×9 = 279cm2

2x+5= 31

x=13cm

x+5= 18cm
