<h2>
3p+6
</h2>
Step-by-step explanation:
8p+7−(5p+1)
=8p+7+−1(5p+1)
=8p+7+−1(5p)+(−1)(1)
=8p+7+−5p+−1
=8p+7+−5p+−1
=(8p+−5p)+(7+−1)

But say we didn't know the formula. We can chop out the 4 by 4 square and we have two 45/45/90 triangles side 4 left over, so two 4 by 4 squares,
A = 2(4)(4) = 32
We can think of this as 12 by 4 rectangle with two 4 by 4 right triangles chopped out:
A = 12(4) - 2(1/2)(4)(4) = 48 - 16 = 32
