14 cm and ALS and PLT are semicircles.
3. The length of a rectangular field is increased by 50% and its breadth
is decreased by 50% to form a new rectangular field. Find the
percentare chanm in th​

Answer 1

Answer:

As =14 cm

Diameter of the semicircles =14cm

Radius = 7 cm

Area of two semi circles = pie 7 or r square=154 cm square

Area of square = 14 × 14 = 196 cm square

Area of shaded region =196‐154=42 cm square.

Answer 2

the area of the square=14*14=196sq.cm

the side of square=diameter of the circle

then radius =14/2=7cm

area of the two semicircles=2*1/2*22/7*7*7=154sq.cm

area of shaded region=196-154=42sq.cm
