Question

Heelo HELP ME PLEASE

Answer 1

We can't do all those in one answer.   I'll try the first page.

1 a.  There are lots of ways to do these. They probably want you to see that the base of P is 4 units and the height is 6 units, so area (1/2)(4)(6)=12

Answer: 12

Let's try it with Pick's Theorem.  Pick says interior points I count as 1 and boundary points B count as one-half, and we overcount by 1,

area = I + B/2 - 1

I count 9 interior points, I=9, and B=8 boundary points,

area = 9 + 8/2 - 1 = 12

Math works!

b.  Q is a Parallelogram

c.  Base 4, height 5, area = 4(5) = 20

2.

L=2W

P=2L+2W=24

2(2W)+2W=24

6W=24

W=4 cm

L=8 cm

I'll leave it to you to draw the 4×8 rectangle on the grid.

3.

L=3W

LW=48

(3W)W=48

3W²=48

W²=48/3=16

W=4

L=3W=12

4×12 rectangle to draw.

4.

b=2h

(1/2)bh = 16

(1/2)(2h)h = 16

h² = 16

h = 4

b = 8

Draw any triangle with base 8cm, height 4cm.

5.

b=2h

bh=50

2h²=50

h²=25

h=5

b=10

Parallelogram base 10, height 5

6.

That perimeter has 3 long sides of the rectangle and 3 short sides, and one extra piece that's the difference, 7-4=3cm.

P= 3(7+4) + 3cm = 36 cm
