mrk me as brainliest nd thanks me plsss
Step-by-step explanation:
We have
Perimeter of Rhombus = 40cm
One diagonal = 16 cm
Therefore
4* side = 40
Side = 10 cm
So by heron's formula
S = 16 + 10 + 10 /2 = 18
√ 18 ( 18 - 16 ) ( 18 - 10 ) ( 18 - 10 )
= √ 18 * 2 * 8 * 8
= 8 √ 2 * 3 * 3 * 2
= 8 * 2 * 3
= 48 sq cm
Area of one triangle = 48
Area of two triangles = 48 * 2 = 96 sq cm
Area of rhombus = 96 sq cm
