Question

Help a sis out ??

Answer 1

Answer:

B

Step-by-step explanation:

let base be b then height h = 2b + 4

The area (A) of a triangle is calculated as

A = $\frac{1}{2}$ bh ( b is the base and h the height ) , then

A = $\frac{1}{2}$ b(2b + 4) ← distribute parenthesis

A = b² + 2b

When b = 16 , then

A = 16² + 2(16) = 256 + 32 = 288 in²
