Question

7. Find the area of the shaded regions.
​

Answer 1

Answer:

100 cm^2

Step-by-step explanation:

Area of the rectangle = l*b = 10*16=160cm^2

Area of the triangle= 1/2 bh [ h=15 cm(by pythagoras) ; b= 8cm]

=> 1/2*15*8 = 60 cm^2  

Area of shaded region = area of rectangle - area of triangle

= 160 cm^2 - 60 cm^2 => 100 cm^2
