Question

What is the area of the triangle, given each square on the grid represents $1$ unit${}^2?$

• A. $32uni{t}^2$
• B. $16uni{t}^2$
• C. $26uni{t}^2$
• D. None of the above

Answer 1

The correct option is B $16uni{t}^2$


From the diagram above,

Base $=8units$

Height $=4units$

$\therefore Area=\frac{1}{2}\times Base\times Height$

$⟹Area=\frac{1}{2}\times 8\times 4$

$=16$ unit${}^2$
