Question

14.1 A babes is in the form of a rectangle ABCD in which
AB= 20 cm and BC l4cm. A semi-circular bastion
with BC as diameter is cut-off find the area of remaining part​

Answer 1

Answer:

give me the figure of that question

Answer 2

Answer:

Given :length of the babes=20cm

breadth =14 cm

Diameter of semicircular bastion=14cm

since, radius=14/2= 7cm

Step-by-step explanation:

Now Area of Remaining part=Area of babes - Area of bastion

$= l \times b - (\pi \: r {}^{2} \div 2) \\ = 20 \times 14 - 22 \div 7 \times 7 \div 2 \times 7 \\ = 280 - 11 \times 7 \\ = 280 - 7 \\ = 203cm {}^{2}$
