from a rectangular sheet 124cm X 120cm 80, circles of radius 7cm each are cut find the area of the remaining sheet​

Answer 1

Answer:

2560 cm²

Step-by-step explanation:

area of rectangle = l× b

124 × 120 = 14880cm²

area of one circle = 2πr²

2 × 22/7 × 7× 7 = 154cm²

area of 80 circles= 154 × 80 = 12320 cm²

area of remaining sheet = 14880 - 12320 = 2560 cm²
