Question

A leaf, which when placed on a grid sheet with grids of $1c{m}^2$ each, covers 10 half squares and 5 complete square grids. What is the area covered by the leaf?

• A. $10c{m}^2$
• B. $12c{m}^2$
• C. $15c{m}^2$
• D. $13c{m}^2$

Answer 1

The correct option is A $10c{m}^2$

Given, area of each square grid = $1c{m}^2$

The leaf covers 5 complete squares and 10 half squares.

So, area occupied by the leaf

$=5\times 1c{m}^2+10\times \frac{1}{2}c{m}^2$

$=5c{m}^2+5c{m}^2=10c{m}^2$
