Question

in the figure 11. 14 ,st=5cm ,qr =9cm. the area of the large triangle is 50cm2. what is the area of shaded region​

Answer 1

Answer:

Step-by-step explanation:

Area of bigger ∆=50 cm

Area of smaller ∆=1/2*ST*QR

=1/2*5*9

=22.5 cm

Area is shaded region=Ar. of bigger ∆ - Ar. of smaller ∆

=50 cm - 22.5 cm

=27.5 cm

Therefore, area of shaded region is 27.5 cm.
