The area of the shaded part in figure A and B are 2m² and 49 m² respectively.
Area of the shaded part
To determine the area, we must know the shape of the shaded part.
After identifying the shape, we move further to know the formula for such shape
From the figures given in A, we can see that the shaded region is in form of a triangle
a. The area of a right angle is given as;
The base multiplied by the half the height and vice versa
It is written mathematically as;
Area = 1/ 2 × base × height
Where
base = 2m
height = 2m
Substitute into the formula
Area = 1/ 2 × 2 × 2
Area = 2m²
For figure B, the shaded part is a rectangle
The formula for area of a rectangle is given as;
the width multiplied by the length
Area = width × length
Where width = 7m
length = 7m
Area = 7 × 7
Area = 49m ²
Thus, the area of the shaded part in figure A and B are 2m² and 49 m² respectively.
