Question

find the area of the triangle with the given base and height. b = 3 m and h = 10\frac{1}{2} m enter the correct number in the box. □ m²

Explanation:

Step1: Recall area formula

The formula for the area of a triangle is $A=\frac{1}{2}bh$.

Step2: Substitute given values

Substitute $b = 3$ and $h=10\frac{1}{2}=\frac{21}{2}$ into the formula: $A=\frac{1}{2}\times3\times\frac{21}{2}$.

Step3: Calculate the product

$A=\frac{3\times21}{2\times2}=\frac{63}{4} = 15.75$.

Answer:

$15.75$
