The area of a square floor on a scale drawing is 64 square centimeters, and the scale drawing is 1 centimeter:3 ft. What is the

Oxana [17]

Answer:

Part a) The area of the actual floor is $576\ ft^{2}$

Part b) The ratio of the area in the drawing to the actual area is $\frac{1}{9}\frac{cm^{2}}{ft^{2}}$

Step-by-step explanation:

we know that

The scale drawing is $\frac{1}{3}\frac{cm}{ft}$

step 1

Find the dimensions of the square on a scale drawing

The area of a square is equal to

$A=b^{2}$

where

b is the length side of the square

$A=64\ cm^{2}$

$64=b^{2}$

$b=8\ cm$

step 2

Find the dimensions of the actual floor

Divide the length of the floor on the drawing by the scale drawing

$8/(1/3)=24\ ft$

step 3

Find the area of the actual floor

The area of a square is equal to

$A=b^{2}$

substitute

$A=24^{2}=576\ ft^{2}$

step 4

Find the ratio of the area in the drawing to the actual area

$\frac{64}{576}\frac{cm^{2}}{ft^{2}}$

Simplify

Divide by 64 both numerator and denominator

$\frac{1}{9}\frac{cm^{2}}{ft^{2}}$

(a) The area of a rectangular parking lot is 7802 m².

Serhud [2]

Answer:

A) Length = 94 m

B) Width = 79 m

Step-by-step explanation:

The area of a parking lot is 7802 m²

Area = length x width

7802 = length x 83

length = 7802 ÷ 83

length = 94 m

The perimeter of a pool is 353 m

Perimeter = 2(length + width)

352 = 2(97 + width)

352 = 194 + 2width

2width = 352 - 194

2width = 158

width = 158/2

width = 79 m

An equation is formed of two equal expressions. The points that lie on the graph are (-4,9), (-3,6), and (1, -6).

<h3>What is an equation?</h3>

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

If we plot the equation 3x+y=-3 on the graph and the dots (-3,6),(-4,9),(-5,0),(2,-3),(3,0), and (1,-6) on the graph. Then it can be observed that the points that lie on the line are (-4,9), (-3,6), and (1, -6).

Hence, the points that lie on the graph are (-4,9), (-3,6), and (1, -6).
