The area of a rectangle is 265.5 m2. If the length is 18 m, what is the perimeter of the rectangle?
julia-pushkina [17]

Answer:

65.5 m

Step-by-step explanation:

Step 1. Find the width of the rectangle.

The formula for the area of a rectangle is

A = lw

Data:

A = 265.5 m²

l =     18    m

Calculation:

265.5 = 18w

w = 265.5/18 = 14.75 m

Step 2. Calculate the perimeter

The perimeter (P) of a rectangle is the sum of the lengths of its sides.

P = 2(l + w) = 2(18 + 14.75) = 2 × 32.75 = 65.5 m

The perimeter of the rectangle is 65.5 m.

What is the height of the building pictured below if its shadow is 100 ft. long?
Evgen [1.6K]
Yeah.. baby, do the SOH CAH TOA with the hula hoop

\bf &#10;sin(\theta)=\cfrac{opposite}{hypotenuse}&#10;\qquad \qquad &#10;% cosine&#10;cos(\theta)=\cfrac{adjacent}{hypotenuse}&#10;&#10;\\ \quad \\&#10;% tangent&#10;tan(\theta)=\cfrac{opposite}{adjacent}&#10;

so.. hmmm we have in the picture, an angle, and two sides,
actually, is the "adjacent" side, and the "opposite"

so.. which  of those ratios give us only
the angle
the adjacent side
the opposite side?

ahhha!, is Ms tangent
so  \bf tan(\theta)=\cfrac{opposite}{adjacent}\implies tan(42^o)=\cfrac{h}{100}

solve for "h"
