Answer:
area = 22,272
Step-by-step explanation:
area = length * width
to calculate the width, we need the first segment using the pythagorean theorem
[tex]87^{2} + x^{2} = 145^{2}[/tex]
[tex]7569 + x^{2} = 21025[/tex]
[tex]x^{2} = 13456[/tex]
[tex]x = 116[/tex]
length = 116 + 140 = 256
so
area = 87 * 256 = 22,272
