Question

16. Area of the Rhombus is 21 sq.cm. If one of its diagonal is 7 cm. then the another diagonal is _______​

Answer 1

Answer:

6cm

Step-by-step explanation:

Area of a rhombus is d1×d2× 1/2

given area = 21

d1 = 7cm

$7 \times x \times 1 \div 2$

$7x \div 2 = 21$

$7x = 42$

$x = 6$

thus the other diagonal (d2) = 6cm
