It is already simplified, three goes into three once but three cant go into 32 without there being a remainder.

Question 1 Find the area of the shaded region. 18 ft 15 ft 8 ft A = ft?

qwelly [4]

Answer:

Step-by-step explanation:

see attached image

shaded area = total area (1) - unshaded triangular area (2)

1. area of a trapezoid = (a + b) * h/2

where a = 8, b = 18, h = 15

Area of trapezoid = (8 + 18) * 15/2 = 195 ft²

2. Area of unshaded triangle = 1/2 (8) 15 = 60 ft²

shaded area = 195 - 60 = 135 ft²

Help me plz will mark brainliest

Ksju [112]

Step-by-step explanation:

Given,

the bigger triangle (∆GFH), <HGF = 90° and <GFH = 60° and GF = 4

In the 30-60-90 triangle, FH = 4×2 = 8

or you can find it like this,

cos60 = 4/FH

FH = 4/cos60 = 8

Now, I is the midpoint of FH, so, FI = 8/2 = 4

now for ∆FGI,

<GFI = 60°, GF = 4, FI = 4, it's a equilateral triangle, so we can say GI = 4

Now we need to find the height of ∆FGI, for that,

area of ∆FGI = (√3/4)×4² = 4√3 = 6.92820323..

So height (GJ) = 2×area/side = 2×4√3/4 = 2√3 = 3.46410162.. [height of ∆GFI (Because altitude is perpendicular distance from a point) = GJ, given]

now, in ∆GJI, GJ = 2√3, GI = 4 and <GJI = 90° (since itsy altitude, the angle will be a right angle, i.e. 90°)

So, JI = √{4²-(2√3)²} = 2

Area = 2×2√3/2 = 2√3 = 3.46410162.. = 3.46 (rounded to the nearest hundredth)

If the cost to purchase and install carpet is $4 per square foot, how much will it cost to put carpet in the family room and hal

andrey2020 [161]

The first step is to section the given daigram. It would be shown in the diagram below

Looking at the diagram,

Area of family room = 5.5 * 24 = 132 square feet

Area of hallway = 15.5 * 4 = 62 square feet

Total area to be covered with carpet is

132 + 62 = 194 square feet

Since the cost per square foot is $4, then the cost of putting carpet in the family room and hallway is

194 * 4 = $776* 4 = $776
