Question

Q2 The shape of a garden is rectangular in the middle and semi-circular at the ends as shown in the diagram. Find the area and the perimeter of this garden [Length of rectangle is 20 – (3.5 + 3.5 meters]

​

Answer 1

Step-by-step explanation:

according to question,

area of garden-- area of plot -area of house

=25×25 - 20×15

= 625-300

= 325m²

that answer is according to to figure

the figure consists of a rectangle and two hemisphere of same size which will form a circle

length of rectangle = 20-(3.5+3.5) = 20-7 = 13 m

breath = 7m

therefore

area of rectangle= length × breadth

= 13×7= 91m²

area of circle= πr²

22/7×7/2×7/7= 38.5m²

area of garden=area of rectangle+area of circle

=. 91+38.5 = 129.5 m²

perimeter of garden= 2×length of rectangle+circumference of circle

2×13+2×22/7×7/2

26+22

48 m
