• A. (i) $28c{m}^2$ (ii) $15c{m}^2$ (iii) $38.76c{m}^2$ (iv) $24c{m}^2$.
• B. (i) $2c{m}^2$ (ii) $15c{m}^2$ (iii) $38.76c{m}^2$ (iv) $24c{m}^2$.
• C. (i) $28c{m}^2$ (ii) $1c{m}^2$ (iii) $38.76c{m}^2$ (iv) $24c{m}^2$.
• D. None of these

Answer 1

The correct option is A (i) $28c{m}^2$ (ii) $15c{m}^2$ (iii) $38.76c{m}^2$ (iv) $24c{m}^2$.

We know Area of parallelogram $=$ Base $\times$ Height $=bh$

$\left(i\right)$ Given: $b=7cm,h=4cm$

$\therefore$ Area of parallelogram $=bh=7\times 4=28c{m}^2$

$\left(ii\right)$ Given: $b=5cm,h=3cm$

$\therefore$ Area of parallelogram $=bh=5\times 3=15c{m}^2$

$\left(iii\right)$ Given: $b=5.1cm,h=7.6cm$

$\therefore$ Area of parallelogram $=bh=5.1\times 7.6=38.76c{m}^2$

$\left(iv\right)$ Given: $b=4cm,h=6cm$

$\therefore$ Area of parallelogram $=bh=4\times 6=24c{m}^2$

Hence, $\text{A}$ is the correct option.
