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.

Rectangle RSTU and the image R’S’T’U’ are graphed on the coordinate grid below.
Ksju [112]

The rectangle  R’S’T’U’ is a 90° counterclockwise rotation of RSTU so options (A) and (C) will be correct.

<h3>What is a rectangle?</h3>

The rectangle is a geometrical figure in which opposite sides are equal.

The angle between any two consecutive sides will be 90 degrees.

Area of rectangle = length × width.

Perimeter of rectangle = 2( length + width).

Given the rectangle RSTU if we plot it then it becomes a major horizontal rectangle.

If we transpose into R’S’T’U’ then it rotates 90 degrees counterclockwise and becomes a major vertical ractangle.

Hence the rectangle RSTU will rotate 90° counterclockwise to form  R’S’T’U’.

(05.06)A chocolate bar measures 50 mm wide, 90 mm long, and 3 and 1 over 2 mm high. Will’s Wrapping Company is making a wrapper
grandymaker [24]
The surface area of a rectangular prism is always:

A=2(xy+xz+yz), where x, y, and z are the three dimensions of the prism.

A=2(50*90+50*3.5+90*3.5)

A=2(4500+175+315)

A=2(4990)

A=9980 mm^2
