Question

7. Find the area and the perimeter of the shape which is rectangular in the middle and semicircular at the ends * 14 m 54 m​

Answer 1

Answer:

perimeter = 54+14=68

area=lb= 14*54=756

Answer 2

Step-by-step explanation:

Total area of garden = area of the rectangular portion + the sum of the areas of the perimeter of semi circle

= 1.b + 2 × 1/2 π r ^2

= (13×7) m^2 + (2×1/2×22/7×3.5×3.5)m^2

= (91 + 38.5)m^2

= 129.5 m^2

Perimeter of the garden = 2×Length of rectangular portion + circumference of the circle

= (2×13+2×22/7×3.5)m

=(26+22)m=48 m

{Ans=48m}
