Question

date: _ review: week 9 3 what is the area? 4 solve

Explanation:

Step1: Calculate the area of the first triangle

The formula for the area of a triangle is \(A=\frac{1}{2}\times base\times height\). For the first triangle, the base \(b = 7m\) and the height \(h=4m\).

$$A_1=\frac{1}{2}\times7\times4$$

$$A_1 = 14m^{2}$$

Step2: Calculate the area of the second triangle

For the second triangle, the base \(b = 8mm\) and the height \(h = 3mm\).

$$A_2=\frac{1}{2}\times8\times3$$

$$A_2=12mm^{2}$$

Answer:

The area of the first triangle is \(14m^{2}\) and the area of the second triangle is \(12mm^{2}\)
