The area of a rectangular wall of a barn is 85 square feet. Its length is 12 feet longer than the width. Find the length and width of the wall of the barn.

Length = 17 feet, Width = 5 feet

Step-by-step explanation:

Given:

The area of a rectangular wall of a barn is 85 square feet.

Its length is 12 feet longer than the width.

Question asked:

Find the length and width of the wall of the barn.

Solution:

Let width of a rectangular wall of a barn =

As length is 12 feet longer than the width.

Length of a rectangular wall of a barn =

As we know:

Subtracting both sides by 85

As width can never be in negative, hence  width of a rectangular wall of a barn = = 5 feet

Length of a rectangular wall of a barn =

Therefore, length and width of the wall of the barn is 17 feet and 5 feet respectively.

step-by-step explanation:

i looked it up

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.
