Answer 2

Answer:-

★ Given:

• Diagonal¹ of rhombus = 7.5 cm

• Diagonal² of rhombus = 12 cm

★ To Find:

• Area of rhombus

★ Formula Used:

• Area of rhombus = ½ × Diagonal¹ × Diagonal²

★ Solution:

Area of rhombus

= ½ × Diagonal¹ × Diagonal²

= ½ × 7.5 × 12

= 7.5 × 6

= 45cm²

Hence, Area of rhombus is 45 cm².

★ Formula to be remembered:-

▪︎Area of rhombus = ½ × Diagonal¹ × Diagonal²

▪︎Area of parallelogram = Base × Height

▪︎Area of square = Side × Side

▪︎Area of rectangle = length × breadth

▪︎Area of triangle = ½ × Base × Height

Or

By Heron's Formula.
