Answer:

Area = 129.5m^2

Perimeter = 48m

Step-by-step explanation:

Given

See attachment

Required

Determine the area and the perimeter of the garden

Calculating Area

First, we calculate the area\ of\ the\ rectangle

A_1 = L * B

Where:

L = 20-(3.5 +3.5)

B = 7

So:

A_1 = (20 - (3.5 + 3.5)) * 7

A_1 = (20 - 7) * 7

A_1 = 13 * 7

A_1 = 91

Next, we calculate the area of the two semi-circles.

Two semi-circles = One Circle

So:

A_2 = \pi r^2

Where

r = \frac{7}{2}

A_2 = \frac{22}{7} *  (\frac{7}{2})^2

A_2 = \frac{22}{7} *  \frac{49}{4}

A_2 = \frac{22}{1} *  \frac{7}{4}

A_2 = \frac{22*7}{4}

A_2 = \frac{154}{4}

A_2 = 38.5

Area of the garden is

Area = A_1 + A_2

Area = 91 + 38.5

Area = 129.5m^2

Calculating Perimeter

First, we calculate the perimeter of the rectangle

But in this case, we only consider the length because the widths have been covered by the semicircles

P_1 = 2 * L

Where:

L = 20-(3.5 +3.5)

So:

P_1 =2 * (20-(3.5 +3.5))

P_1 =2 * (20-7)

P_1 =2 * 13

P_1 =26

Next, we calculate the perimeter of the two semi-circles.

Two semi-circles = One Circle

So:

P_2 = 2\pi r

Where

r = \frac{7}{2}

P_2 = 2 * \frac{22}{7} * \frac{7}{2}

P_2 = \frac{2 * 22 * 7}{7 * 2}

P_2 = \frac{308}{14}

P_2 = 22

Perimeter of the garden is

Perimeter = P_1 + P_2

Perimeter = 26 + 22

Perimeter = 48m
