Question

If a rectangle occupies $40$ complete grids of area $2m{m}^2$ each, then what is the total area occupied by the rectangle?

• A. $40m{m}^2$
• B. $80m{m}^2$
• C. $20m{m}^2$
• D. $10m{m}^2$

Answer 1

The correct option is B $80m{m}^2$

Given, number of grids occupied by the rectangle = 40

Area occupied by each grid = 2 $m{m}^2$

$\therefore$ Total area occupied by the rectangle = 40 × 2 $m{m}^2$ = 80 $m{m}^2$
