Surface area of a rectangular pyramid = A + 1/2 p s

Where:

A = area of the base

p = perimeter of the base

s= salnt height = 5 in

A = Area of a rectangle = length x width = 8 x 4 = 32 in2

Perimeter of the base = 2 lenght + 2 width = 2(8)+2(4) = 24 in2

SA = 32 + 1/2 * 24 * 5 = 92 in2

Can someone help! I know the answer I just need step by step!

Answer:

$4 \sqrt{2}$

Step-by-step explanation:

Rewrite 32 as the product of 16 and 2:

$\implies \sqrt{32}=\sqrt{16 \cdot 2$

Apply exponent rule $\sqrt{a \cdot b}=\sqrt{a}\sqrt{b}$

$\implies \sqrt{16 \cdot 2}=\sqrt{16}\sqrt{2}$

Rewrite 16 as 4²:

$\implies \sqrt{16}\sqrt{2}=\sqrt{4^2}\sqrt{2}$

Apply exponent rule $\sqrt{a^2}=a$

$\implies \sqrt{4^2}\sqrt{2}=4 \sqrt{2}$
