Question

find the area of shaded regain
​

Answer 1

Answer:

1074.08cm²

Step-by-step explanation:

Use Herons formula

Area = √ p ( p − a ) ( p − b ) ( p − c )

where p is half the perimeter, or

a + b + c /2

Area of triangle ABC is 1320cm²

Area of triangle ABD by herons formula is 245.92cm²

Area of shaded region is (1320-245.92)cm² = 1074.08cm²
