Question

Sara bought a triangular-shaped piece of wood with a height of $8$ inches and with a base of $3$ inches. She plans to cover the front with a piece of fabric, how much fabric $\left({\text{in inch}}^2\right)$ will she need?

• A. 12

Answer 1

The correct option is A 12
Given:

Height of wood = $8$ inches

Base of wood = $3$ inches

Now,

fabric needed = Area of triangular wood

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

$⟹Area=\frac{1}{2}\times 2\times 8inc{h}^2$

$⟹Area=3inc{h}^2$

$\therefore$ Fabric needed = $12inc{h}^2$
