Question

workers at the botanical gardens are building a new triangular pond as show they need to fill the bottom with pebbl one bag of pebbles fills 1 m². how mar bags of pebbles will they need?
(there is an image of a triangle with a base of 3 m and a height of 2.4 m, and also a mention of b = 2 m in another diagram above)

Explanation:

Step1: Identify base and height

Base \( b = 2 \, \text{m} \), height \( h = 2.4 \, \text{m} \)

Step2: Calculate area of triangle

Area \( = \frac{1}{2} \times b \times h = \frac{1}{2} \times 2 \times 2.4 = 2.4 \, \text{m}^2 \)

Step3: Find number of bags

1 bag fills \( 1 \, \text{m}^2 \), so bags needed = area

Answer:

2.4 (rounded up to 3 if whole bags are required, but based on calculation it's 2.4)
