Question

Find the area of rhombas with side 14 cm and altitude5.2cm.If one of its diagonal is 15cm long. Find the length of its other diagonal.​

Answer 1

side =14 cm

altitude = 5.2 cm

area =b× h

=14×5.2=72.8

diagonal length = 15 cm

2nd diagonal lenght be x cm

area =1/2×15×x

72.8=1/2×15×x

x=17.6

Answer 2

Here is your answer mate ...


Given.. Side = 14cm
Altitude/height = 5.2 cm
Diagonal 1 = 15 cm


Area of rhombus = b × h
= 14 cm × 5.2cm
= 72.8cm²

Let the other diagonal be x


Area of rhombus = 1/2 × d⑴ × d⑵

72.8cm² = 1/2 × 15cm × x

72.8cm² = 7.5x

x = 72.8cm²/ 7.5

x = 9.70 cm Ans.


So ,the length of the other diagonal is 9.70cm.
