Question

From the given diagram, calculate the area of the rectangle as shown in the shaded portion.

• A. $28{\text{unit}}^2$
• B. $35{\text{unit}}^2$
• C. $42{\text{unit}}^2$
• D. $49{\text{unit}}^2$

Answer 1

The correct option is B $35{\text{unit}}^2$

Observing the diagram, we see that the rectangle is 5 units high and 7 units long.
And we know that the area of a rectangle equals the product of the two sides.
$\Rightarrow$Area $=\text{length}\times \text{height}$
$\Rightarrow$ Area $=7\times 5=35{\text{unit}}^2$.
