Answer 2

Given :

• The diagonals of rhombus are the 10cm and 5cm

To find :

• It's area

Solution :

d1 = 10 cm

d2 = 5 cm

Area of rhombus = ½ × d1 × d2

= ½ × 10 × 5

= 5 × 5

= 25 cm

∴ Area of rhombus is 25cm

Extra information :

• Volume of cylinder = πr²h
• T.S.A of cylinder = 2πrh + 2πr²
• Volume of cone = ⅓ πr²h
• C.S.A of cone = πrl
• T.S.A of cone = πrl + πr²
• Volume of cuboid = l × b × h
• C.S.A of cuboid = 2(l + b)h
• T.S.A of cuboid = 2(lb + bh + lh)
