Question

the area of the rhombus is 20cmsquare.if one of the diagonal is 5cm the other diagonal is​

Answer 1

Answer:

4 cm

Step-by-step explanation:

Area of rhombus = 1/2 * d¹ *d²

d¹ = 5cm

Area = 20 sq cm

20 = 1/2 * 5 * d²

d² = 8 cm

Answer 2

Answer:

Other diagonal of the rhombus is 8 cm

Step-by-step explanation:

Let two diagonal be a and b

Area of the rhombus = 20 cm square

One of the diagonal a= 5 cm

Area of the rhombus using diagonals is given by

$A=\frac{a\times b}{2}\\20=\frac{5\times b}{2}\\b=\frac{40}{5}\\b=8 cm$

Other diagonal is 8 cm
