Answer 1

Topic

Area

Given

A rhombus has diagonals of length 28 cm and 30 cm.

To Find

The area of given Rhombus.

Formula

The area of a rhombus is

( D₁ × D₂ ) / 2

where

D₁ and D₂ are the diagonals of rhombus.

Solving

D₁ = 28 cm

D₂ = 30 cm

Applying the formula,

Area = ( D₁ × D₂ ) / 2

Area = ( 28 cm × 30 cm ) / 2

Area = ( 840 cm² ) / 2

Area = 420 cm²

Answer

So, the area of given rhombus is 420 cm².
