Question

15. From a rectangular sheet, four
corners in the form of quarter
circles are cut off. A circle from
the centre is also cut off. If the
radii of all the circles are 1 cm
B
and the rectangle measures 8 cm by 5 cm, find the
area of the remaining sheet after all the pieces are
cut off.​

Answer 1

Answer:

33.71cm^2

Step-by-step explanation:

4 quadrants form a cricle

so, Area of shaded region = Area of rectangle - area of 2 circles

l×b - 2×22/7×r^2

8×5 - 44/7×1

40 - 44/7

280/7 - 44/7 = 236/7 = 33.71cm^2

therefore area of shades region = 33.71cm^2
