Question

the area of trapezium of height 12cm is 288cm sq. if one of the parallel sides is 21 then find the other side.

Answer 1

Answer:

Step-by-step explanation:

Area of Trapezoid = ((a+b)/(2))×h

Area is given A=288cm.sq

Height of Trapezoid h=12cm

One of side is given

Assume given side is a=21cm

So

((21+b)/(2))×12=288

By simplifying we get value b

b=27cm

So the dimension of other side of Trapezoid is 27cm
