Answer:
158 in²
Step-by-step explanation:
<u>Surface area</u>
A = 2·(l·w + l·h + w·h)
= 2·(3in·8in + 8in·5in + 3in·5in)
= 2·(24in² + 40in² + 15in²)
= 2·(79in²)
= 158 in²

Let 's complete our quadrilateral to a rectangle ; and subtract from it the area highlighted in red

Answer:
B
Step-by-step explanation:
<em>a/b × d/c = a×d / b×</em><em>c</em>
Multiply the numerators 1st.
x × x = x^2
Next is the Denominator.
x+3 × x+2
now try to multiply each term of the 1st expression with the 2nd.
x × x + x × 2 + 3 × x + 6
x^2 + 2x + 3x + 6
x^2 + 5x + 6
Write the numerator & denominator in their respective places.
x^2 / x^2 + 5x + 6
