1. Write a formula for finding the area of a parallelogram.
le

The formula for area of a parallelogram is either or .

Step-by-step explanation:

If base and vertical height of a parallelogram are given, then the area of the parallelogram is:

Where, b is base and h is the vertical height of the parallelogram.

If measures of both diagonals are given, then the area of the parallelogram is:

Where, are the two diagonals of the parallelogram.

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.
