प्रश्न
Find the missing value.
Diagonal (d1) | Diagonal (d2) | Area |
12 mm | 180 sq.mm |
उत्तर
Given diagonal d2 = 12 mm; Area of the rhombus = 180 sq.m
`1/2` (d1 × d2) = 180
`1/2` (d1 × 12) = 180
d1 × 12 = 180 × 2
d1 = `(180 xx 2)/12`
d1 = 30 mm
Diagonal d1 = 30 mm
Tabulating the results we have
Diagonal (d1) | Diagonal (d2) | Area |
30 mm | 12 mm | 180 sq.mm |
