Answer:
357 mi²
Step-by-step explanation:
The shape is made of a triangle and a half-square
we will calculate the area of each one
let A1 be the area of the half-circle:
A1= (10²*π)/2 = 50π mi²
Let A2 be the area of the triangle:
A2= 10*20=200 mi²
let At be the total area:
At =A1+A2= 200+50π =357.07≈ 357 mi²
