Total area of the garden = Area of the rectangular portion + The sum of the areas of the pair of semi-circles
=l.b+2× 1/2 π r square
=(13×7)m square + (2×1/2×22/7×3.5 × 3.5 msquare
=(91+38.5)m square
=129.5m square
Perimeter of the garden =2× length ofrectangular portion + circumference of the circle
=( 2×13+2× 22/7 ×3.5 )m
=(26+22)m=48m
