Rational Area and Irrational Perimeter Question for a Rhombus

Look at Picture

Correct C.

Step-by-step explanation:

Rhombus with side √5 units has perimeter

P = 4 √5 units which is irrational number

Rhombus with diagonals with lengths √2 and √18 has area

A = (d₁ · d₂)/2 = (√2 · √18)/2 = (√36)/2 = 6/2 = 3 units²

A = 3 units² which is rational number

God is with you!!!

its d. the first coordintaes are 10,32

step-by-step explanation:

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.
