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
