Question

The grid you see below is in the shape of a rectangle. What is the area, in square
units, of the shaded part?​

Answer 1

Answer:

The area of the shaded region is $18\ \text{units}^2$.

Step-by-step explanation:

On the attached figure, a rectangle is shown. It is required to find the area of the shaded part. The shaded part forms a triangle. The area of a triangle is given by :

$A=\dfrac{1}{2}\times b\times h$

b is base and h is height

From this figure, each box is a square of side 1 unit say.

Its height will be 4 units and its base is 9 units

So,

$A=\dfrac{1}{2}\times 9\times 4\\\\A=18\ \text{units}^2$

So, the area of the shaded region is $18\ \text{units}^2$.
