Answer:
6
(assuming the units is in centimetres)
Step-by-step explanation:
Hi, hope this helps!
Method 1:
Calculate this shape as a trapezium. This is a trapezium because it has one pair of parallel sides. The way to calculate the area of a trapezium is this:
- Half the sum of the parallel sides
- Multiply the perpendicular height between them
In this case, 4 and 2 are parallel, so we add them together (4 + 2 = 6) then we divide by two (6 ÷ 2 = 3). Then we multiply our answer by the perpendicular length between the two parallel sides (assuming the side on the left is at a right-angle, 3 x 2 = 6).
Method 2:
Calculate this shape as a rectangle + a triangle. If you split the shape so the pointy bit on the right becomes a triangle and the left becomes a square, you can calculate the area without knowing the formula for calculating a trapezium (see above ^).
- Area of the square / rectangle = length x width = 2 x 2 = 4
- Area of the triangle = 1/2 x length x width = 2 x 2 x 1/2 = 4 x 1/2 = 4 ÷ 2 = 2
Then we add the two areas together (4 + 2 = 6).
I hope this helped and I wasn't waffling on :)

Formula: d = √(x2-x1)²+(y2-y1)²
d = √(11-3)²+(11-5)²
d = √8²+6²
d = √64+36
d = √100
d = 10
Best of Luck!

Answer:
(b) √55
Step-by-step explanation:
The right triangles in this geometry are all similar, so the ratio of long side to short side is the same:
y/5 = 11/y
y² = 55 . . . . . . multiply by 5y
y = √55 . . . . . take the square root
__
And x=4√5 by looking at ratios of short side to hypotenuse.
The possible combination of the number of peaches and apricots they can get for $5 is 2 peaches and 5 apricots.
<h3>What is the possible combination?</h3>
The equation that represents the total cost of peaches and apricots is:
Total cost = (number of peaches x cost of one peach) + (number of apricots x number of apricots)
$5 = ($0.85 x p) + ($0.55 x a)
Total cost of buying 1 peach and 8 apricots:
($0.85 x 1) + ($0.55 x 8) = $5.25
Total cost of buying 2 peaches and 5 apricots:
($0.85 x 2) + ($0.55 x 5) = $4.45
Total cost of buying 3 peaches and 7 apricots:
($0.85 x 3) + ($0.55 x 7) = $6.40
Total cost of buying 4 peaches and 3 apricots:
($0.85 x 4) + ($0.55 x 3) = $5.05
