Question

Area of a trapezium is 351 sq. cm, its parallel
sides are in the ratio 5 : 8 and their difference is
18 cm. Find the sum of measure of other two
equal sides of trapezium if length of its diagonals
are equal​

Answer 1

Step-by-step explanation:

Area of trapezium=1/2(a+b)×h

Area of trapezium=351m²

Parallel side 'a'=5x

Parallel side'b'=8x

Height=18

Acc.to question

1/2(5x+8x)×18=351

(5x+8x)×9=351

13x×9=351

13x =351/9

13x=39

x=39/13

x=3

parallel side'a'=5x=5×3=15cm

parallel side'b'=8x=8×3=24cm
