rhombus is a parallelogram we can find its area by the formula of parallelogram
= base × height
= 8cm × 3cm
= 24cm
let the another angle = x
according to the question
1 /2 ×diagonal 1 × diagonal 2 = 24cm
1/2 × 6 cm × x = 24cm
3cm × x = 24 cm
x = 24 cm / 3cm
x= 8cm
= base × height
= 8cm × 3cm
= 24cm
let the another angle = x
according to the question
1 /2 ×diagonal 1 × diagonal 2 = 24cm
1/2 × 6 cm × x = 24cm
3cm × x = 24 cm
x = 24 cm / 3cm
x= 8cm
