Help me with this pls.

Answer 1

Answer:

Area of figure is 51 cm²

Step-by-step explanation:

We need to find the area of the figure given.

The figure is basically a combination of 3 rectangles.

Adding area of all the rectangles will give the area of the figure.

The formula used is: $Area\:of\:rectangle=Length\times Width$

Area of rectangle 1:

Length = 7 cm

Width = 3 cm

The area will be:

$Area\:of\:rectangle=Length\times Width\\Area\:of\:rectangle=7\times 3\\Area\:of\:rectangle=21 \:cm^2$

The area of rectangle 1 is 21 cm²

Area of rectangle 2

Length will be: 7-4 = 3cm

Width will be: 3 cm

The area will be:

$Area\:of\:rectangle=Length\times Width\\Area\:of\:rectangle=3\times 3\\Area\:of\:rectangle=9 \:cm^2$

The area of rectangle 2 is 9 cm²

Area of rectangle 3

Length will be: 7cm

Width will be: 3 cm

The area will be:

$Area\:of\:rectangle=Length\times Width\\Area\:of\:rectangle=7\times 3\\Area\:of\:rectangle=21 \:cm^2$

The area of rectangle 3 is 21 cm²

The total area of the figure will be:

Area of figure = Area of rectangle 1 + Area of rectangle 2 + Area of rectangle 3

Area of figure = 21+9+21

Area of figure = 51 cm²

So, Area of figure is 51 cm²
