Question

A sheet od paper is 30 cm long and 20 cm broad. If triangle of 15 cm base and 10 cm height cut out of this. find the area of remaining piece of paper?

Answer 1

Answer:

525 cm2

Step-by-step explanation:

Area of sheet =30*20=600 cm2

area of triangle was cut

=1/2*15*10=15*5=75 cm2

The area of remaining piece of paper:

600-75=525 cm2

Answer 2

Answer:

Remaining Area is 525 cm².

Step-by-step explanation:

Length of rectangular paper = 30 cm

Breadth of the rectangular paper = 20 cm

Length of the triangle = 15 cm

Height of the triangle = 10 cm

Area of paper = Area of rectangle = length × width = 30 × 20 = 600 cm²

Area of triangle =1/2 × base × height = 1/2  × 15 × 10 = 15 × 5  = 75 cm²

Remaining paper = 600 - 75 = 525 cm²

Therefore, Remaining Area is 525 cm².
