In the given below figure , find the area of the unshaded region ,if the length and breadth of the
shaded region is 2114
cm and 1818
cm.
Answers
Step-by-step explanation:
To find the area of unshaded region,
area of big rectangle - area of small rectangle
area of big rectangle = 30 1/5 × 24 1/7
= 30.2 × 24.142...
= 729.0884
area of small triangle = 21 1/4 × 18 1/8
= 21.25 × 18.125
= 385.156
729.0884 - 385.156 = 343.9324
The answer is 343.9324
Correct option is
Correct option isD
Correct option isD19.27 cm2
Correct option isD19.27 cm2Area of a circle =πr2
Correct option isD19.27 cm2Area of a circle =πr2 =722×3×3
Correct option isD19.27 cm2Area of a circle =πr2 =722×3×3 =28.29cm2
Correct option isD19.27 cm2Area of a circle =πr2 =722×3×3 =28.29cm2∴ Area of the shaded region =28.29+28.29+228.29
Correct option isD19.27 cm2Area of a circle =πr2 =722×3×3 =28.29cm2∴ Area of the shaded region =28.29+28.29+228.29 =70.73cm2
Correct option isD19.27 cm2Area of a circle =πr2 =722×3×3 =28.29cm2∴ Area of the shaded region =28.29+28.29+228.29 =70.73cm2Area of the rectangle =15×6=90cm2
Correct option isD19.27 cm2Area of a circle =πr2 =722×3×3 =28.29cm2∴ Area of the shaded region =28.29+28.29+228.29 =70.73cm2Area of the rectangle =15×6=90cm2∴ Area of the unshaded region =(90−70.73)cm2
