Question

The area of rhombhus is 480cmsq and one of its diagonal measures 48cm .find the length of the other diagonal the length of each of its sides and its perimeter

Answer 1

area of rhombus = 1/2*d1*d2
480= 1/2*48*d2
480*2= 48*d2
960/48 = d2
20= d2
diagonal2 =20cm

side =
$\sqrt{10 {}^{2} + 24 {}^{2}}$
$\sqrt{100 + 576}$
$\sqrt{676 } = 26$
side 26cm

perimeter =4*26
=104cm
