Answer:

136 mm²

Step-by-step explanation:

A=a^{2} +2a\sqrt{\frac{a^{2} }{4} } +h^{2}

A=6^{2} +2(6)\sqrt{\frac{6^{2} }{4} } +8^{2}

A=36 +12\sqrt{\frac{36 }{4} } +64

A=36 +12\sqrt{9 } +64

A=36 +12(3)+64

A=36 +36+64

A = 136

What fraction is 1 yard 2 feet and 6 inches
MA_775_DIABLO [31]

Answer:

Make sure you convert these numbers into one unit. Convert everything to yard. Just convert the feet and inches in yard since it's the biggest unit, and then add them together. You should get a fraction not a whole number.
