Answer:
24cm²
Step-by-step explanation:
Perimeter of rectangle ABCF = 20 cm
One of the sides AB = 6 cm (AB)(Let it be L)
other side of Rectangle=B.
Perimeter of Rectangle = 2 (Length + width)
20 = 2(L+W) = 2(6 + W)
=6+B
10=6+B
B = 10-6
B = 4 cm
Width of Rectangle, W = 4 cm (BC)
Length of side of trapezium, CD = BD - BC = 9 - 4 = 5 cm
And length of EF = 3 cm
Area of Trapezium = ×(CD+EF)×CF
×(5+3)×6
×6
4×6=24
You can solve this problem by using the pythagorean theorem.
Where the a- and b-values represent the sides of the triangle. Since the park is a sqaure, each side is equal. This means that both the a-value and the b-value are the same. Now, you must find the c-value.
145^2 + 145^2 = c^2
21,025 + 21,025 = c^2
42,050 = c^2 *now square root each side of the equation.*
205.06 = c
The length of the diagonal line is 205 meters.
