THEA THEA Geometry & Data Analysis 1

Question 1

What is the area of a rectangle with a length of 12 cm and a width of 8 cm?

Accepted Answer

96 cm²

Answer

Area of a rectangle = length × width = 12 × 8 = 96 cm².

Question 2

The perimeter of a square is 36 inches. What is the length of one side?

Accepted Answer

9 inches

Question 3

What is the area of a triangle with a base of 10 m and a height of 6 m?

Accepted Answer

30 m²

Answer

Area of a triangle = ½ × base × height = ½ × 10 × 6 = 30 m².

Question 4

A circle has a radius of 7 cm. What is its approximate area? (Use π ≈ 3.14)

Accepted Answer

153.86 cm²

Answer

Area = π × r² = 3.14 × 7² = 3.14 × 49 ≈ 153.86 cm².

Question 5

Two angles are supplementary. One angle measures 65°. What is the measure of the other angle?

Accepted Answer
