Question

1. a rectangular garden is 30 ft × 18 ft. draw using scale 1 in = 3 ft.

。drawing dimensions:?

。perimeter:?

。area:?

Explanation:

Step1: Find drawing dimensions

Given scale \(1\) in \( = 3\) ft.
For length: \(\frac{30}{3}=10\) in
For width: \(\frac{18}{3} = 6\) in

Step2: Calculate perimeter of drawing

Perimeter of rectangle \(P=2(l + w)\)
\(P = 2(10+6)\)
\(P=2\times16\)
\(P = 32\) in

Step3: Calculate area of drawing

Area of rectangle \(A=l\times w\)
\(A=10\times6\)
\(A = 60\) in²

Answer:

• Drawing dimensions: \(10\) in \(\times6\) in
• Perimeter: \(32\) in
• Area: \(60\) in²
