Question

Area of rhombus with diagonal 18 is 135cm² find other diagonal ​

Answer 1

Answer: 15cm

Step-by-step explanation:

To find the area of a rhombus, multiply the lengths of the two diagonals and divide by 2 (same as multiplying by 1/2): The sides and angles of a rhombus: The sides of a rhombus are all congruent (the same length.) Opposite angles of a rhombus are congruent (the same size and measure.)

18*x*1/2 = 135

x = 15

Answer 2

Answer:

$\frac{1}{2} \times d1 \times d2 = 135 \\ d2 = \frac{135 \times 2}{18 } \\ d2 = 15cm$
