To find the area you multiply the length by the width.
W = the width, and you are told the length is 5 meters longer, so the length would be (W +5)
Now multiply those together to equal 20,000 square meters:
w(w+5) = 20,000
Just use the Pythagorean Theorem
(9 +x)^2 = 15^2 + x^2
x^2 + 18x + 81 = 225 + x^2
18x = 144
x = 8
So the three sides of the triangle are
15, 8 and 17
Answer:
110.9
Explanation:
Find the height of the triangle by using the Pythagorean theorem.
a^2 + b^2 =c^2
(16/2)^2 + b^2 =c^2
b^2= 192
b or height = 13.86
Area of triangle = (b*h)/2
Area of triangle = (16*13.86)/2
Area of triangle = 110.9
Answer:
It is the first one
Step-by-step explanation:
It is the first one because they are all the same shape. In figure D it is thicker than A,B, and C
