What’s the answer to this problem , figure out the area and perimeter of this triangle
Zigmanuir [339]

Answer:

                Area = 67.5 m²

        Perimeter = 69 m

Step-by-step explanation:

<h3>Area of triangle:</h3>

   b = 27 m  & h = 5 m

     \sf \boxed{\text{\bf Area of triangle =$\dfrac{1}{2}bh$}}

                                   \sf = \dfrac{1}{2}*27*5\\\\     =\dfrac{135}{2}\\\\= 67.5 \ m^2

<h3>Perimeter of triangle:</h3>

       Perimeter = sum of all sides

                         = 27 + 34 + 8

                         = 69 m
