Question

hi guys help me answer this two questions plzzzz

Answer 1

hello frnd!!

here's ur answer...

1.given:-

base=18cm

height=12cm

therefore area=b×h

=18×12

=216cm²

2.
let the diagnols of the rhombus be 4x and 3x.

area of the rhombus=384cm²

1/2×d1×d2=384cm²

1/2×4x×3x=384cm²

1/2×12x²=384cm²

12x²=384/1×2/1

12x²=768

x²=768/12

x²=64

x=√64

x=8cm

hence, length of the 1st diagonal=4x

=8×4

=32cm

2nd diagonal=3x

=3×8

=24cm

hope this helps...
