Write the formula and find the area.
a. a square 6 meters on each side
• We will use the formula [tex] \tt A=S²[/tex] in finding the area of a square, in which A stands for Area while S is a side.
[tex]\begin{array}{l} \tt A=S {}^{2} \\ \tt A=(6 \: m) {}^{2} \\ \tt A=36 \: m {}^{2} \end{array}[/tex]
• The area of the given square is 36 square meters.
b. a triangle with 5-meter base and 7 meters height
• In order to find the area of a triangle, we'll use the formula [tex] \tt A=\frac{base \: \times \: height}{2}[/tex], in which A stands for the Area.
[tex]\large\begin{array}{l} \tt A=\frac{\tt b×h}{2} \\ \tt A= \frac{5 \: m \: \times \: 7 \: m}{2} \\ \tt A= \frac{35 \: m {}^{2} }{2} = 17.5 \: m {}^{2} \end{array}[/tex]
• The area of the given triangle is 17.5 square meters.
