Question

The height of the trapezium is 40 cm2 and height is 4 cm. What will be the length of one of the parallel sides if another side’s length is 13 cm.
(a) 14 cm
(b) 7 cm
(c) 3.5 cm
(d) 8 cm​

Answer 1

7 cm

Step-by-step explanation:

Area of trapezium = 40 cm ^2

Height = 4 cm

Length of one side = 13 cm

1/2 l(sum of all parallel sides) = 1/2*4(13+x) =40

2(13+x) =40

= 40/2 = 20(13+x)

x = 20-13 = 7 cm

CHECK --- 1/2*4(13+7) = 40 cm

So,our answer is correct.

Answer 2

14 centimetres this the answer mate
