Find the area of the compound shape below.pls help

trapecia [35]

Answer:

22cm²

Step-by-step explanation:

For the area of triangle,

base = 2 + 2 + 2 = 6cm

height = 4cm

Area = 1/2 x base x height

= 1/2 x 6 x 4

= 12cm²

For area of the rectangle,

length = 5cm

breadth = 2cm

Area = length x breadth

= 5 x 2

= 10cm²

Area of compound shape = 12 + 10 = 22 cm²

An excursion party had $2.00 to pay in total, but before the bill was paid 10 people from the party went away, and those that re

KatRina [158]

Answer:

20 people

Step-by-step explanation:

Let x be the number of people initially. We can find the amount each of them has to pay at first

2 / x

But when 10 people walk away, the remaining (x - 10) has to pay 10 cents more to get the same total of $2. This would means

$(\frac{2}{x} + 0.1)(x-10) = 2$

From here we can perform cross multiplication

$2 - 20/x + 0.1x - 1 = 2$

$0.1x - 20/x - 1 = 0$

Multiply both sides by 10x:

$x^2 -10x - 200 = 0$

$x= \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$

$x= \frac{10\pm \sqrt{(-10)^2 - 4*(1)*(-200)}}{2*(1)}$

$x= \frac{10\pm30}{2}$

x = 20 or x = -10

Since x can only be positive we will pick x = 20
