Answer:

$Area = 27cm^2$

$P=23cm$

Step-by-step explanation:

Required

The area and the perimeter

Solving (a): The area

The shape is a composite figure withe following characteristics:

Rectangle 1: 3cm by 5cm

Rectangle 2: 2cm by 6cm

So, the area is the sum of the areas of both rectangles

$Area = 3cm * 5cm + 2cm*6cm$

$Area = 15cm^2 + 12cm^2$

$Area = 27cm^2$

Solving (b): The perimeter

This is calculated as:

$P=3cm + 5cm + 2cm+6cm + 2cm + 5cm$ --- sum of all lengths

$P=23cm$

Answer:

I hope my drawing explains well lol... h = 16

Step-by-step explanation:

So basically first you need to find x (the one in the drawing), by doing so, you just have to use the formula,

$speed = \frac{distance}{time}$

You substitute in the speed and the time given,

$0.4 = \frac{x}{30} \\ x = 12$

Then, you use the Pythagorean theorem,

$h = \sqrt{ {20}^{2} - {12}^{2} } \\ h = 16$
