Answer:
area of garden=area of rectangle+area of 2semicircle
length of rectangle=20 m
we see that breath=diameter of semicircle
that is 7+7=14
radius of circle=7
area of rectangle=L×B
area of semi circle=1/2 πr²
20×14+2×1/2×22/7 ×7×7
280+ 22×7
280+154
434m²
perimeter of garden= 2×length of rectangle+ perimeter of 2 semi circle
2×20+2×1/2×2×22/7×7
40+44
84m
