Question

the area of trapezium is 252 sqcm and the distance between it's parellel sides is 24cm. if one of the parellel sides is 7cm of length, find the other length.​

Answer 1

Answer:

Step-by-step explanation:

Area of the trapezium = 24 cm ²

Height (h)                    = 4 cm

Length of one side      = 7 cm

Let the length  be 'x'

area of a trapezium =1/2×h×(a+b)

1/2×4×(7+x) = 24

2×(7+x)    = 24

7+x           = 24/2

x = 12-7

x = 5 cm.
