What is the area of the rectangle?

Answers

Answer 1

Answer:

Answer:

40 units²

Step-by-step explanation:

First find the length of one of the longer sides. This length is found using the Pythagorean Theorem:

L = √[ 8² + 4² ] = √[ 80 ] = 4√5.

Similarly, the width is W = √[ 2² + 4² ] = √[ 20 ] = 2√5.

The area of the rectangle is A = L * W = (2√5)(4√5) = 8(5) = 40 units²

The scale on a map shows that 200 miles is represented by 5 inches on a map.Which proportion can be used to find the distance on the map,x, that represents 50 miles?

Answers

If you would like to know which proportion can be used to find the distance on the map that represents 50 miles, you can calculate this using the following steps:

200 miles ... 5 inches
50 miles ... x inch = ?

200 * x = 5 * 50
x = 5 * 50 / 200
x = 1.25 inch

The correct result would be x = 5 * 50 / 200.

Answer:

200 miles over 5 inches = 50 miles over x inches

200/5 = 50/x = 200x/250 =

x = 250/200 = 1.25

1.25 inches = 50 miles
