Answer:

B.)21.4

Explanation

A(-4, 3), B(0,2), C(2,4) and D(0,-3)

AB = √(1²+4²) = √17 =4.12

BC = √(2²+2²) = √8 = 2.83

CD = √(2²+7²) = √53 = 7.28

AD = √(4²+6²) = √52 =7.21

Perimeter = 4.12+2.83+7.28+7.21 = 21.44

To the nearest tenth the answer is 21.4.

bixtya [17]

Answer:

1. 1800 square cm.

2. See below

3. 45000 square cm.

Explanation:

Part 1

The dimensions of the drawing are 36cm by 50cm.

$\begin{gathered} \text{The area of the board}=36\times50 \\ =1800\operatorname{cm}^2 \end{gathered}$

Part 2

Given a scale factor, k

If the area of the scale drawing is A; then we can find the area of the actual board by multiplying the area of the scale drawing by the square of k.

Part 3

$\begin{gathered} \text{Area of the scale drawing}=1800\operatorname{cm}^2 \\ \text{Scale Factor,k=5} \end{gathered}$

Therefore, the area of the actual drawing will be:

$\begin{gathered} 1800\times5^2 \\ =45,000\operatorname{cm}^2 \end{gathered}$
