Question

The area of a rhombus is 240 cm2 and one of its diagonals is 30 cm. Find the length of the

other diagonal.​

Answer 1

Explanation:

Area of rhombus= 1/2 ab

$240 = \frac{1}{2} \times 30 \times b$

$240 = 1 \times 60 \times b$

$240 = 60b$

$b = \frac{240}{60}$

b= 4

other diagonal = 4 cm
