Question

A room has a triangular flag with a height of 40 cm and a base of 20 cm. What is the formula to find the area of the flag?

Answer 1

Answer: 1/2bh, 400 cm^2

Explanation:

Base (b) = 20 cm
Height (h) = 40 cm

Area (A) = 1/2 * b * h = 1/2bh

Therefore,
= 1/2 * b * h
= 1/2 * 20 * 40
= 1 * 10 * 40
= 10 * 40
=> 400

Area = 400 cm^2

Answer 2

A= 1/2 x bace x hight

Explanation:

A= 1/2 x 20 x 40 =400

A= 400
