Kelly has a rock garden with a length of 6 feet. She constructs a scale model of the rock garden using the scale 1 inch:2 feet.

melamori03 [73]

Answer:

Part a) 3 inches

Part b) Yes, her scale model drawing will fit on the piece of paper 8.5 by 7 inches

Step-by-step explanation:

we know that

The scale drawing is

$1\ inch:2\ feet$

That means

1 inch in the model represent 2 feet in the actual

Part a) What is the length of the garden in her model?

we know that

The length of the garden is 6 feet in the actual

Find out the length of the garden in her model, using proportion

$\frac{1}{2}\ \frac{in}{ft}=\frac{x}{6}\ \frac{in}{ft}\\\\x=6/2\\\\x=3\ in$

Part b) If the width is 5 inches for the scale model and the scale is still 1 inch to 2 feet, will her scale model drawing fit on a piece of paper that is 8.5 inches by 7 inches? Why or why not?

we know that

The model width is described as 5 inches. Both the 3-inch length and the 5-inch width are less than the 8.5 inch and 7 inch dimensions of the paper Kelly is using.

therefore

She can easily draw her model on that size paper.

What is the perimeter and area of this figure? Round to the nearest whole number.

Tpy6a [65]

Answer:

Step-by-step explanation:

This figure is quarter of a circle.

=> Perimeter = π/2r + 2r

=> 5π + 10

=> 5(3.14) + 10

=> 15.7 + 10

=> 26 units

Area = πr²/4

=> 3.14 x 100 / 4

=> 25 x 3.14

=> 79 sq. units
