Question

Help with number one a and b is both parts of number one

Answer 1

Solving the operation_

We are given two figures that represent a garden. We are asked to determine its areas.

The shape of figure A is a rectangle of 9 ft by 12 ft. The area of a rectangle is the product of its dimensions therefore, we have:

`A_A=\left(9ft\right)\left(12ft\right)`

Solving the operations:

`A_A=108ft^2`

The shape of figure B is a circle of radius 5ft. The area of a circle is:

`A_B=\pi r^2`

Where "r" is the radius. Substituting we get:

`A_B=\pi\left(5ft\right)^2`
`A_B=25\pi ft^2`

In decimal notation, the area is:

`A_B=78.54ft^2`
