pls help me fast
find the area
Answers
Answer:
Step-by-step explanation:
Area= Area of triangle ABC+Area of triangle CAD
As the figure is bisected by a diagonal, so both figures formed (by the diagonal) will be equal to each other
So we can say that,
Total area of figure= 2(Area of triangle ABC)
To find base AB,
Using pythagoras theorem,
(Hypotenuse)² = (Base)² + (Perpendicular)²
()² = (AB)² + ()²
140 = (AB)² + 112
(AB)² = 28
AB = (we will take AB as root 28 only as its real value is a long decimal number)
Area of triangle = 1/2 x base x height
= 1/2 x x
Area of full figure = 2(area of triangle)
= 2 x 1/2 x x
= x
We cannot multiply further, so area would be x unit².
