the height of the triangle is 4cm and the base width is 18 cm and the base length is 18 cm what is the surface area of a square
Gnesinka [82]

Answer:

The surface area is 664 cm²

Step-by-step explanation:

A=a^{2} +2a\sqrt{\frac{a^{2}}{4}  } +h^{2}          Use this equation to find the surface area

A=18^{2} +2(18)\sqrt{\frac{18^{2}}{4}  } +4^{2}   Simplify

A=324 +36\sqrt{\frac{324}{4}  } +16       Simplify

A = 324 + 36√81 + 16         Simplify

A = 324 + 36(9) + 16           Simplify

A = 324 + 324 + 16             Simplify

A = 664 cm²
