Swarnajit Dey 5 years, 9 months ago

Ok thanks

0Thank You

Yogita Ingle 5 years, 9 months ago

Given perimeter of the rhombus is 28m.

Therefore side × 4 = 28m
=> Side = 28/4
=> Side = 7m

Verification :-

Perimeter of rhombus = side × 4
= 7 × 4
= 28m

Hence, the side of the rhombus is 7m.

In area, the side of the rhombus is base.

Therefore b × h = 28m²
=> 7 × h = 28m²
=> h = 28/7
=> h = 4cm
