The area of a triangle is A = ½ × base × height = ½ × 8 × 5 = 20 cm².

Question 2

A rectangle has a length of 12 cm and a width of 5 cm. What is its perimeter?

Accepted Answer

34 cm

Answer

Perimeter of a rectangle = 2(length + width) = 2(12 + 5) = 2(17) = 34 cm.

Question 3

What is the circumference of a circle with a radius of 7 cm? (Use π ≈ 3.14)

Accepted Answer

43.96 cm

Answer

Circumference = 2πr = 2 × 3.14 × 7 = 43.96 cm.

Question 4

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

Accepted Answer

115°

Answer

Supplementary angles sum to 180°, so the other angle = 180° − 65° = 115°.
