Question

perimeter of rhombus is 52 cm if a(x,-7) b(2x,5) find the value of x

Answer 1

Answer:

Distance between A and B will be =

√(x-2x)²+(-7-5)²

√(x²+144)

Now,

since each sides of rhombus are equal in length ,

each side = 52/4 = 13 cm

equating both we get,

√(x²+144) = 13

x²+144 = 169

x² = 169-144 = 25

x = ±5 (Ans)
