Question

find the area of shaded region​

Answer 1

Answer:

the answer is

Step-by-step explanation:

the area of rectangle is

80×100

= 8000

the area of the triangle is

1/2×60×50

30×50= 1500

area of shaded region is

8000 - 1500

6500

Answer 2

Answer:

Step-by-step explanation:

firstly find the area of rectangle = l x b =80 x 100 =8000

for area of triangle=

s=a+b+c/2

s=50+50+60/2=80

$area=\sqrt[2]{s(s-a)(s-b(s-c)}$

area of triangle=(80*30*30*20)^1\2

=1200

so area of shaded region=8000-1200=6800
