Question

A certain board is 16 dm by 9 dm. A can of paint will cover 100 sq. m. Will it be enough to cover the entire
board?​

Answer 1

Step-by-step explanation:

The given board is rectangular.

$l = 16 \: m$

$b = 9 \: m$

Area of rectangle

$= l \times b \\ = 16 \times9 \\ = 144 \: {m}^{2}$

The can of paint will cover only 100 m².

144 > 100

:. The paint will not be enough to cover the entire board.
