Question

the length of two diogonals of a rhombus is 13 cm and the length of one diagonal is 10 cm find the length of other diagonal and the area of Rhombus

Answer 1

sum of two signal=13cm
one diagonal=10
other diagonal=13-10
=3
area of rhombus=1/2×d1+d2
1/2×10+3=6.5

Answer 2

Find the length of the other diagonal:

two diagonals = 13 cm

one diagonal = 10cm

The other diagonal = 13 - 10 = 3cm

Find the area:

Area = 1/2 ( diagonal 1 + diagonal 2)

Area = 1/2 ( 13)

Area = 7.5 cm²

Answer: 7.5 cm²
