Step-by-step explanation:

CSA = 32 m sq

= 2(l + b) h = 32

= (l + b) h = 16

TSA = 86 m sq

= 2(lb + bh + lh) = 86

= (lb + bh + lh) = 43

= lb + h(l+b) = 43

= lb + 16 = 43

lb = 43 - 16 = 27

lb = 27

Answer 2

Answer:

6. $\left(1.5x-4y\right)\left(1.5x+4y+3\right)=\frac{9}{4}x^2+\frac{9}{2}x-16y^2-12y-4$

The expression after the comma is the simplest form so I have no idea what's that for. I expand it by means of multiplying the first term (1.5x) in the first bracket with every term in the second bracket, then multiply the second term (4y) with every term in the second bracket to obtain the results above. Not sure if that's what you want.
