Answer:
How are we suppose to answer this on this website?
Step-by-step explanation:
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 =
bh ( b is the base and h the height ) , then
A =
b(2b + 4) ← distribute parenthesis
A = b² + 2b
When b = 16 , then
A = 16² + 2(16) = 256 + 32 = 288 in²
8x5 = 40
3x2 = 6
40 - 6 = 34
answer:
area of shaded = 34
