Answer 1

no

Answer 2

ok

Answer 3

\[A = (2 \times A_{tri}) + A_{rect1} + A_{rect2} + A_{rect3}\]
\[A= (2 \times (\frac{b \times h}{2})) + (L_{1} \times W_{1})+ (L_{2} \times W_{2})+ (L_{3} \times W_{3})\]
BUT
\[L_{1} = L_{2} = L_{3}\]
so
\[A= (2 \times (\frac{b \times h}{2})) + (L_{1} \times (W_{1}+ W_{2}+ W_{3}))\]

Answer 4

o.o okayyyy

Answer 5

Then just substitute known values and compute the numerical answer.

Answer 6

o.o okay um so 8times 8tiejms 10 times 9 1/2?
