Find the area of the following figure |
|
Answer» (a) Area of parallelogram = Base x Height = (12 x 7) cm2 = 84 cm2 (b) r = Radius of semi-circle = 3.5 cm ∴ Area of semi-circle = \(\frac12 \pi r^2\) \(= \frac 12 \times \frac{22}7 \times 3.5\times 3.5\) \(= 19.25\, cm^2\) (c) Area of shape/figure = Area of semi-circle + Area of triangle \(= \frac12\pi r^2 + \frac12\times \) Base \(\times\) Height \(= \frac 12 \times \frac{22}7 \times 3.5\times3.5+\frac 12 \times 3.5\times 3\) \(= 19.25 + 5.25\) \(= 24.50 \,cm^2\) |
