Question 1

How many feet are in 2 miles?

Accepted Answer

10,560 feet

Answer

There are 5,280 feet in one mile, so 2 miles = 2 × 5,280 = 10,560 feet.

Question 2

A map has a scale of 1 inch = 50 miles. If two cities are 3.5 inches apart on the map, what is the actual distance between them?

Accepted Answer

175 miles

Answer

Multiply the map distance by the scale factor: 3.5 × 50 = 175 miles.

Question 3

What is the area of a trapezoid with parallel sides of 8 cm and 12 cm and a height of 5 cm?

Accepted Answer

50 cm²

Answer

Area of a trapezoid = ½(b₁ + b₂) × h = ½(8 + 12) × 5 = ½ × 20 × 5 = 50 cm².

Question 4

If a square has a perimeter of 36 cm, what is its area?

Accepted Answer

81 cm²

Answer

Each side = 36 ÷ 4 = 9 cm; area = 9² = 81 cm².
