A scale drawing of a square has a side length of 5 millimeters. The drawing has a scale of 1 mm : 5 km. Find the actual perimeter and area of the square.

Answers

Answer 1

Answer:

Answer:

Actual Perimeter = 100 km

Actual Area = 625 km²

Step-by-step explanation:

A scale drawing of a square has a side length of 5 millimeters.

The drawing has a scale of 1 mm : 5 km (which represents 1 mm is equal to 5 km)

We need to find the actual measurement of 5 mm square on scale.

1 mm = 5 km

5 mm = 5 × 5 km

= 25 km

The actual length of the side of square is 25 km

Now, we find the perimeter and area of the square.

Perimeter of square = 4 × side

= 4 × 25

= 100 km

Area of the square = side × side

= 25 × 25

= 625 km²

Hence, The actual perimeter is 100 km and area of the square is 625 km²

Justin wants to use 188ft. Of fencing to fence off the greatest possible rectangular area for the garden. What dimensions should he use what will be the area of the garden

Answers

Hello,

Let x the length
y the width

2*(x+y)=188 ==>x+y=94
A= x*y must be maximized

A=x*(94-x)=-(x²-2*47*x+47²)+47²=-(x-17)²+2209
A est maximize if x=47
x=47 =>y=94-47=47 (a square!!!)
Area=47²=2209 (ft²)
