HAI FRIEND, PLEASE MARK IT AS BRAINLIEST IF HELPED
PLEASE FOLLOW ME
FORMULA FOR CALCULATING THE AREA OF QUADRILATERALS IS 1/2(d)(h1+h2)
GIVEN AREA OF QUADRILATERAL IS 510sq cm
GIVEN LENGTH OF DIAGONAL (d)=30
510=30/2(2h) {h+h=2h}
510=30h
510/30=h
51/3=h
17=h
therefore, the lenth of its corresponding heights each =17cm

Answer:
your answer is 17
Step-by-step explanation:
the corresponding heights means the second diagonal
so area of a rhombus = 1/2 *d1 * d2
= 1/2*30*(h+h) { there are two heights on both side of the first diagnols and are equal}
510 =1/2*30*2h
510*2/30=2h
34=2h
34/2=h
17=h
hence the length of both equal corresponding heights is 17cm each.
