The area of a Trapezium is 475 CM and its height is 19 cm find the length of the two parallel side is one side is 4 CM greater than the other
Answers
Answer:
Step-by-step explanation:
. Let the other side be x cm
Area of tapezium= 1/2*sum of parallel side * height
475=1/2*(4+x) * 19
475=2+x/2*19
25-2=x/2
23=x/2
11.5cm=x
Step-by-step explanation:
Let the 1st parallel side be x cm Then the 2nd parallel side be( x+4) cm Area of trapezium =1÷2(sum of the parallel sides) ×height 475=1÷2(x+(x+4))×19 475= 1÷2 (2x + 4)×19 25=x+2 x=23cm 1st parallel side =23cm 2nd parallel side =23cm + 4cm =27cm
