Answer 2

Answer:

Area of Remaining piece of paper is 525 cm².

Step-by-step explanation:

We are Given that

Length of paper = 30 cm

Width of the paper = 20 cm

Length of the triangle = 15 cm

Height of the triangle = 10 cm

We have to find: Area of the remaining paper.

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

$Area\:of\:triangle=\frac{1}{2}\times base\times height=\frac{1}{2}\times15\times10=15\times5=75\:cm^2$

Area of remaining paper = 600 - 75 = 525 cm²

Therefore, Area of Remaining piece of paper is 525 cm².
